Who says you can’t make your own consumer electronics? David A. Mellis, a co-creator of Arduino who now is starting a PhD in Leah Buechley’s group, High-Low Tech, at the MIT Media Lab, has shared his Fab Speakers, an open source, portable speaker project:

These portable speakers are made from laser-cut wood, fabric, veneer, and electronics. They are powered by three AAA batteries and compatible with any standard audio jack (e.g. on an iPhone, iPod, or laptop).

Why open source them? Mellis says he designed the speakers to be affordable and easy to assemble, in the hopes that he would “see changes or additions that I didn’t think about and to have those changes shared publicly for others to use or continue to modify.” Speakers are perhaps ideal for this exercise: the housing matters, both aesthetically and functionally, and because a speaker is something relatively straightforward and simple, it’s easy to imagine modifications that retain the basic role of the design.

Big-league design blog Core77 takes note of what sharing this design can mean, as Mellis turns to designer Sarah Pease to imagine an alternative housing:

Here’s a great example of what can happen when experimental research is documented and posted on the web with plenty of explanation and resources. RISD student Sarah Pease, a junior in Furniture Design, took part in an independent study with the High-Low Tech Group at MIT’s Media Lab this past Fall.

Sarah Pease turns to something you probably already have in your house:

Using readily available household items and basic construction methods allow for even further customization and flexibility of the Fab Speakers. Varying jar shapes/sizes can be mixed with alternate feet for different looks.

High-Low Tech Research Group Project’s Jarring Effect

Building speakers was once a common activity, to the point that many, many musicians made their own speakers or amps or simple effect circuits. For all the excitement over DIY these days, a lot of people don’t have this experience – but with Internet documentation, the time is right for more.

Indeed, I’m keen to hear from people who do have experience building speakers: what might improve the sound quality of this design, and looks aside, what would be the best housing shapes and materials?

In the meantime, I’ll have to give this a try:

I have a bunch of jars, so I may need to give the jars a try here.

Gibson Guitar has announced in a press release they’re acquiring the Stanton Group, which includes, aside from the well-known Stanton DJ brand, KRK monitoring products and Cerwin-Vega loudspeakers.

It’d be easy to see this as a guitar company buying a DJ company, but it’s more than that. KRK and Cerwin-Vega are speaker/monitoring brands. Stanton and Cerwin-Vega each have footholds in the larger consumer arena, not just the pro world, a detail Gibson is quick to emphasize. And Gibson themselves have quietly, steadily grown beyond just guitars. The new “Gibson Pro Audio” banner is added to a list of brands that Gibson reels off: “Epiphone, Dobro, Kramer, Steinberger, Tobias, Echoplex, Electar, Flatiron, Slingerland, Valley Arts, Maestro, Oberheim, Baldwin, Sunshine Piano, Take Anywhere Technology, J&C Fischer, Chickering, Hamilton, Wurlitzer.” But it would seem dropping the “Guitar” from the name would be realistic.

There are two interesting details to the way the press release is worded. First, the lead is that Gibson’s move is “part of its continued expansion as a lifestyle brand.” That’s perhaps going to send a chill down the spine of anyone who prefers to focus explicitly on “musicians.” Gibson CEO Henry Juszkiewicz even says the move “allows us access to 20 in 20 consumers instead of the one in 20 we currently hit.” That contrasts with the emphasis of, say, organizations like NAMM who talk about the general market of “musicians,” not only “lifestyle,” whatever you take that to mean. On the other hand, this is really nomenclature we’re talking here; the question I have is how “lifestyle” actually translates into a strategy, and how well it works for Gibson.

The other detail is more interesting. Gibson and Stanton Group reps each stress the potential for overlapping R&D. Juszkiewicz has touted R&D projects in the past, though largely centered around new guitar tech. We’ll see if the two companies can deliver on that R&D promise and do something really innovative. I have no idea what that’d mean in this case, so if anyone cares to speculate, I’m all ears.

Anyone?

Gibson Guitar Acquires Market-Leading Pro Audio Companies KRK, Cerwin-Vega!, and Stanton [PR Newswire]

Online chatter has in past not been very kind to Gibson on its past acquisition record, so I expect some people will raise the spectre of at least one acquisition again. Let’s see… comments…

I don’t personally view this as flame-bait; Gibson’s a perfectly-respectable guitar maker and I imagine there could be some smart business opportunity here, especially with Stanton together with Gibson in Nashville. However, let’s consider: the names Gibson and Stanton, guitars and DJing. I imagine some flame-broiled comment thread on the Internet somewhere.

And yes, reasons to be skeptical:

Promises of this sort of R&D synergy could easily fail to materialize. And whether Gibson can manage these essentially unrelated businesses is an enormous question mark. There aren’t a whole lot of acquisition success stories in this business.

You might need to be an internationally-touring DJ to buy one, at EUR750, but the Travelteq Trip Sound suitcase is awe-inspiring at least as a design gimmick. The aluminum roll-around is designed first and foremost as a suitcase, as in the things that hold your laptop and clothes when you’re on the road, and is even sold as such – no gimmicks, just an ultra-high-end way of toting luggage. But purchase the Trip Sound option, and you can fold an entire sound system into said suitcase.

What keeps it a gimmick is, unfortunately, power. The Trip Sound System isn’t the most powerful thing around — two 15W, 2.5-inch drivers make it too weak for busking or on-the-spot DJ sets. Think of it as boom box, not PA, and for that, it certainly beats most of the things you could drop into a carry-on. It’ll also play from batteries up to 12 hours, depending on playback volume, or can connect to power via a universal power supply. You can also dock mobile devices, or top off a laptop.

WIthout opening the entire suitcase, you can also get quick access to compartments for phones, newspapers, and such, as well as a padded laptop compartment. Fold out legs, and the suitcase doubles as a chair.

Check out the full specs on the dizzying Travelteq site, which itself seems to be designed for people resistant to motion sickness. (Scroooollling… augh!)

Presumably the price is covered by the construction, interchangeable textiles, rugged, ultra-premium… stuff. You can read their explanation. It’s nothing if not drool-worthy as fantasy. And apparently globe-trotting DJs do desire them – Gui Boratto, Andy Sherman, and – so say rumors – Armin van Buuren own one, says our tipster Brandon Carlyle. (Thanks!)

All in all, though, this serves as a painful reminder of certain laws of space, weight, and power that restrict a lot of what we might do with sound. Your shirts take up a certain amount of space, and so does anything that produces a certain amount of sound. It’s unquestionably a cool fashion accessory, at least. There’s something to which you can aspire, should you aim for a lucrative ascent to the top of DJing: design fetish travelware. (Hey, for some of us design nerds, it beats the better-known perks.)

For a generation of musicians of nearly every genre, the laptop has become an instrument. It’s easy to take for granted, but the rise of the computer for music has been remarkable. Less than twenty years ago, real-time digital synthesis and audio processing was the domain of expensive, specialized workstations. Now, $700 per seat can buy you a full-blown musical rig, with the computer hardware, gestural input courtesy the Nintendo Wii controller, and even a DIY speaker made from IKEA salad bowls. The next challenge is to make this setup as flexible and reliable as possible. Enter Linux.

According with the laptop’s graduation to instrument status, laptops orchestras have spread worldwide, inspired especially by the innovative Princeton Laptop Orchestra (“PLOrk”) directed by Dan Trueman and Perry Cook. PLOrk’s alumnus Ge Wang has even gone on to greater fame making applications for the iPhone via ocarina and T-Pain app developer Smule. The sounds of these ensembles may sometimes be strange, but by pushing laptop performance, the groups are a great place to look for how to get the most out of computer music, whatever your tastes may be.

Virginia Tech’s L2Ork’s claim to faim is that it’s a laptop orchestra powered by Linux. Why does that matter? For one, it makes a big difference on cost. By using Linux-powered netbooks, they’ve slashed the per-student cost from that of the Mac laptops used in some other ensembles, on a machine that’s more compact. Far from making sacrifices to save money, the result is actually  greater reliability, flexibility, efficiency, and audio performance.

As with the PLOrk ensemble, L2Ork combines expressive input with open-ended digital sound making production, localizing the sound near the computer itself using hemispherical speakers. In this way, the laptop instrument can attempt to learn something from acoustic instruments, which are played with human gestures and have sound sources that are positioned physically where the instrument is.

L2Ork

You don’t have to enroll at Virginia Tech to apply these lessons to your own music making, however. You can apply the lessons of the L2Ork ensemble to put together your own Linux audio machine. They’ve even further-documented the process of making PLOrk’s signature “salad bowl” speakers. And you can do it all without breaking the bank.

I got the chance to speak with Dr. Ivica Ico Bukvic, director of the Linux Laptop Orchestra and the DSISIS Interactive Sound and Intermedia Studio at Virginia Tech.

CDM: What is your software rig for this ensemble?

Ivica: We basically use Ubuntu 9.04 (vanilla) with our own custom-built rt kernel, which apart from solid performance also offers full support of standby/hibernate/external monitor, webcam, wireless, bluetooth, etc. We also have various patches/scripts that deal with chronic UI bugs (e.g. order of panel icons in gnome getting trashed whenever a resolution is changed).

Basically, our configuration supports every single functionality of MSI Wind netbooks, which we use as the backbone of the orchestra.

FWIW, our setup offers pretty darn cool price point. The entire setup (MSI Wind, UA-1G soundcard, hemi speaker, [Nintendo] Wiimote/Nunchuk, all the cables/accessories, headset, and case) comes down to approximately $700/seat which arguably makes it as cheap as an iPhone setup, except you get to enjoy flexibility of using a laptop (ok, a netbook .

What music software are you using?

Our audio platform is currently exclusively [multimedia patching environment] Pd-extended 0.42.5 (running through [low-latency audio server] JACK) which we’ve also customized to allow advanced GUI setup (e.g. per-patcher configurable background, menu/ontop/resize/scrollbar toggles, what is IMHO better scrolling algorithm than what we currently have) as well as integrated several new objects whose source we are about to release (our multithreaded version of the Wiimote object for Linux has been already posted on the Pd-list a couple weeks ago, and it fully supports Wiimotes/Nunchuks without any interruptions to the Pd’s audio thread).

What do you do to get Ubuntu running properly?

Basically, it’s lightly-modded Ubuntu 9.04 that allows us to support all the hardware on the netbook, thus offering a quality desktop experience as well as RT audio performance. The kernel is custom-built 2.6.29-rc6-rt3. We have it available for download from a temporary folder off of my personal site
(http://ico.bukvic.net/Linux/). Once we clean everything up we will actually generate a full HD image and offer it for public download in hope to allow people to load that thing and thus allow them to have the best possible out-of-box experience (obviously as far as MSI Wind is concerned).

Is the hemispherical speaker something readers could build?

There are probably dozen videos on the VTDISIS Youtube channel that are designed to help potential L2Ork adopters build their own speakers, from cannibalizing/retrofitting the amps to improve their performance, to building cables and final assembly.

Videos

Rehearsal video shows how the L2Ork work out playing and soundmaking as an ensemble.

Got more questions for the ensemble? Let us know.

I’d definitely like to offer, as well, some information on how to make Ubuntu work this well for you, and how to learn Ubuntu, Pd, JACK, and other free tools, in a way that’s beginner-friendly. That sounds like a decent New Years’ Resolution.

In the meantime, it’s worth mentioning that if you aren’t excited about the prospect of custom-configuring kernels yourself, the Indamixx Linux laptop we’ve featured previously is pre-configured in a similar way; the netbook I’m testing now even runs on the same MSI netbook. And that also, in turn, illustrates how research and volunteer efforts can go hand-in-hand with commercial solutions:

Strings of tour dates and electronic music often mean crowd-friendly dance music, but there’s a growing, impassioned audience for more contemplative concert sounds, too. Composer-musicians Lesley Flanigan and Tristan Perich are pulling into the last stop on an extended tour of their work, here in New York Friday at Galapagos Art Space. For many, electronic music, in particular that made with computers, becomes about abstraction. For this duo, electronics become a chance to grow even closer to the tangible, acoustic sound – techniques they share in workshops as well as performances.

And would you believe… antique harpsichord?

In the tracks below, you can hear some of the results. Lesley’s work begins with harsh, crackling ambient sounds, but move into delicate, sung harmonies. Tristan’s work goes another direction entirely, combining his 1-bit electronics with elaborate keyboard textures. Those become a kind of post-minimalist jam; “Dual Synthesis” even begins to recall the composer György Ligeti’s micro-polyphony. Tristan’s harmonic language is inventive, set into abruptly-shifting, asymmetrical phrases and polyrhythms.

Allow yourself to slip deeper into their musical world, and the sounds become increasingly welcome.

I asked the two artists, known under their solo names as well as part of the ensemble Loud Objects, to send us some sounds and notes from the road. Be sure to catch them tomorrow night if you can, and I hope we’ll get more music from them soon, as well, especially with Tristan’s upcoming 1-bit album due soon. (And naturally, with Loud Objects and Handmade Music, we hope to share some of the electronics behind some of their sounds, too.)

Notes from Tristan and Lesley

We’re on the home stretch of our US tour; we’re sharing a blowout homecoming show with New Amsterdam Records and the NOW Ensemble on December 18th at Galapagos.

The tour has centered on two performances: Tristan’s new composition for antique harpsichord and 1-bit electronics (Dual Synthesis), and Lesley’s work for hand-crafted speaker feedback instruments and voice (Amplifications). We both deal with similar ideas of physicality of electronic sound, treating electric instrumentation as acoustic. Each of our sets has paired traditional instruments (harpsichord and voice) with our own primitive hand-built electronics (1-bit circuits and amplifying feedback circuits). A few of the early shows alternated with Tristan and Kunal Gupta’s noise soldering project, the Loud Objects.

We hit up a multitude of different kinds of spaces, from art galleries in San Francisco, Chicago and Nashville, community-run venues in Providence, St Louis, Denver and LA, colleges like Wesleyan and Ball State, a bar in Milwaukee, to a science museum in Little Rock and a ton of other spaces in between. We also got to debut our new albums: Tristan’s 1-Bit Symphony (which will be officially released by Cantaloupe Music in the Spring), and Lesley’s Amplifications.

It was great to check out the local experimental scenes, and share shows with our favorite musicians along the way, like Joe Grimm, Lucky Dragons, Jib Kidder, Travis Weller and Blevin Blectum. A bunch of people even told us they found out about our work on Create Digital Music.

Oh yeah, we also hosted a couple Loud Objects noise-toy making workshops along the way (you remember how we like to do this ).  One was at Noisebridge in San Francisco and another was at a prep school in Little Rock. We’re hoping to get involved with more schools doing this stuff. You can check out what we’ve been making on loudobjects.com.

Looking forward to finally getting back to NYC!

Digital technology has transformed the listening experience. But there’s little in the way of physical artifacts of that act, and a diminished sense of humanized relationships to an individual being at the other end. From modern radio to Internet-streamed playlists, our listening world is DJed by automated robots in streams that flow through generic, mass-market speakers. The object and the content lack the design intention that imbued, for instance, the gorgeous radio sets of the early 20th Century and the personalities that narrated the programming.

Armed with a lasercutter, designer Matt Brown has a novel concept for how to redesign the act of listening. From the creator’s blog Real Tomato:

For this system, you would have a speaker with an rfid reader, and laser-cut paper radios with rfid chips inside. The radios themselves are designed by musicians, charities, brands, and designers. When the paper radio is placed over the speaker it changes the radio station to what the artist has chosen. Other noises and interactions can be programmed in too. Alec Baldwin’s radio for example could politely ask everyone to turn their lights off from time to time. People could have the paper radios around their house in different rooms. The supremes radio might be a better living room station. This system tries to add a little bit of fun to internet radio, and give people a connection with the artists they choose. The radios themselves would hopefully be cheap and collectible little sculptures, each one accessing unique stations.

The artist, D.A.R.Y.L., is a recent alumnus of Sweden’s Umea institute of Design.

I think we need a new, specialized Creative Commons license that describes “Great Concepts I Probably Won’t Get to Developer Further so Please Go Run with It With Some Credit to Me.” (Okay, maybe with a shorter name.) I love the possibilities this project suggests, if for no other reason than the beautiful sculptures created with the lasercutter.

The works themselves are printed out a single sheet and assembled. THat demonstrates some of the power lasercutters can provide, and the promise they hold for localized production of objects. (Use eco-friendly recycled paper and inks, and this is a consumer product that doesn’t deliver a dropkick to the planet.)

I just interviewed Owen Pallett aka Final Fantasy, and he told me saw a survey that showed some 80% of music journalists listen through music via the built-in speakers in their laptops. That would be terrifying if true – I’m not certain that it is – but regardless, I think there is a clear need to rethink listening processes and objects.

One lesson learned: milk can be incompatible with electronics.

Looks can be a powerful agent for changing how we think about sound. Pairing liquid, organic speakers with equally fluid and dynamic visualizations, the launch of Muon last month in Italy made this principle readily apparent. I’m all about lo-fi, cheap gear here on CDM, but if you absolutely must launch luxurious aluminum speakers with spectacular animated visuals at a posh party in an Italian salon, I sure won’t complain. Pass the prosecco, please?

Details on the installation and how it was done:

Liquid-y Speakers: The speakers themselves were beautiful enough. Designed by UK speaker research center KEF Audio and Ross Lovegrove, a champion of organic, 21st Century design and one of the most respected designers on the planet, the key to the design is super-formed aluminum. The process does for metal something like what vacuum forming does for plastic: you heat sheets of aluminum so they can be molded into unique forms. The speakers themselves are formed out of single, 6-foot pieces of metal, into an acoustically-conceived, flowing form. I haven’t heard them, but we’ve already discussed (at a radically lower price point) why speakers really don’t have to be — or even shouldn’t be — rectangular.

Liquid-y Visualization: And that’s just the speakers. Part of the beauty of digital media is that they can make the invisible and the impossible visible in a dynamic way. So Muon creators employed London’s responsive media firm Moving Brands, who in turn brought in two of our favorite people — responsive media guru Chris O’Shea (see his blog Pixelsumo, and artist and Processing ninja Toxi (aka Karsten Schmidt). Working with creative director David Eveleigh-Evans, the team created a dynamic animation on a huge LED screen that could visualize the sound coming from the speakers and reflect in motion what the speakers do in product design.

How They Did It

The animation isn’t just a pretty visualization; it organically reflects what’s happening with the sound. Performing a spectral analysis of the sound (via a Fast Fourier Transform or FFT), the software uses amplitude levels in different zones of frequencies to produce particle objects, which spring and bob based on polarity, turning the peaks in amplitude in sound into a pulsating pool of fluid. The model itself is actually 3D, but it’s squashed into 2D space (or you can imagine looking at the 3D space from above). The other essential element is that the software looks at a history of amplitudes over time, so that overall changes can be adjusted (a bit like the simple “peak” meter on a consumer stereo EQ).

If you imagine an EQ meter using a pool of mercury instead of simple bars, that’s the basic idea.

The implementation is, as I’d expect from this team, simple and elegant — a few basic elements are tweaked to produce a maximal effect. Here’s the gear (software and hardware) used to pull it off:

Processing, the open-source, Java-based, simple coding environment for graphics and multimedia. (Trust me. You can code in it. Even a 10-line sketch can often be interesting, though sound-related stuff tends to get a lot more involved fast.)

Ess, which is one of a few competing sound libraries for Processing based on the Java sound API. (See also the JSyn-based Sonia, though there seem to be some compatibility issues with that one, and the newer, tongue-twisting Mimin.)
traer.physics, a wonderful and easy-to-use physics library. (I’ve used it in a few projects — a must-download.)

Toxi’s own libraries.

ControlP5 for debugging, a library that places on-screen controls in your sketch. (I imagine it’d also be hugely useful for performance, and can’t believe I haven’t tried it before!)

And don’t forget the ginormous LED screen from Creative Technology, “containing 73,728 full colour LEDs over a 10 x 5 metre floor, using the Barco MiTrix system.” Yum. 73,000 LEDs.

More stuff from Chris on the way. If you’ve got a Processing project for sound, we’d love to hear about it. It’s better-known on the visual side (and a regular subject on Create Digital Motion), but there are still MIDI and audio tasks at which it excels, even if you have access to tools like Max/MSP/Jitter. Right tool for the right job, and whatnot.

While on the subject of Gallo Speakers, here’s about as far as you can get from the baby-sized A’Diva satellites: speakers that tower 78″ tall, pack some 12 4″ aluminum woofers each, and deliver nearly omni-directional sound. Micro speakers (5″ each), yes, but in a slender but tall enclosure.

The Reference 5LS speakers, due third quarter 2007 but shown recently at CES in prototype form, alternate mid-range spheres with tweeter cylinders vertically. The idea is to deal with phase and dispersion issues in a nearly (though not quite) omni-directional speaker. Gallo also showed off a reference amp that would couple with the speakers (the Reference SA).

Anthony Gallo Speakers

Click through for some drool-inducing photos. Now I need to make up a reason to build a sound art installation with these units. (I have until later 2007, after all.)

I never copy and paste press releases, but since people are already asking for more details and there’s nothing up on the Web yet, here’s an excerpt with more of the technical bits (and happily, Gallo tends heavier on actual technical specs in their PR than the usual marketing-speak!):

Scheduled to be released to the public in the third quarter of 2007, the towering speaker stands 78” tall, boasts an incredible 12 custom aluminum 4” woofers and features seven of AGA’s proprietary CDT II tweeters, which possess power-handling, off-axis response and efficiency that approach the textbook definition of ideal. In addition, the Reference 5LS has eight 4″ carbon fiber midrange drivers, each housed it its own 5″ spherical enclosure.

“The Reference 5LS is really the ‘big brother’ of our flagship Reference 3.1,” states Anthony Gallo, award-winning speaker designer and founder of AGA. “While it’s not completely omni-directional, it is the closest any line source has ever come to being omni-directional. This loudspeaker is the culmination of more than 25 years of loudspeaker design research. After a lengthy development cycle, we’re extremely excited to unveil our new flagship to the public at the CES show.”

Many line sources horizontally offset their various drivers, but AGA alternates tweeter cylinders with mid-range spheres – one atop the other – in perfect vertical alignment. Because of this, the phase and dispersion problems caused by driver offset are entirely eliminated.

Capable of being driven by a single, capable amplifier, the 5LS offers the options of bi- or tri-wiring, as well as bi- or tri-amping. Although capable of handling massive power, the crossover-less design and high efficiency of both the CDT II tweeters and carbon-fiber midrange drivers are perfect matches for low-powered, high-performance amplifiers. The first-order low-pass filter used for the bass drivers (The only crossover employed in the 5LS) can be bypassed, enabling the LF enclosure to be driven from the LFE output of a processor, or from a separate amplifier.

At 7” wide by 11” deep, the Reference 5LS sports quite a slender profile. The twelve 4” woofers fire out the back and equal the cone surface of a 15” subwoofer, while offering speed and transparency that a large single driver cannot match. In addition, the Reference 5LS features AGA’s patented S2 Technology, as well as their trademark spherical enclosure, which eliminates any external diffraction.

For even more groundbreaking performance, the company’s optional Reference SA amplifier, which features volume, phase and crossover adjustments, is ideal for this application. The Reference SA allows the speaker to be placed for optimal imaging and soundstaging performance, and then fine-tuned for bass using the SA’s control facilities.

For many of us, our studio and our home are one and the same. The speakers we use to monitor mixes are the ones we use for rehearsals, improvisations, and casual listening. I first got interested in the Anthony Gallo A’Diva series speakers partly because I’ve long admired Gallo’s home speaker products, but also because the Gallos seemed to be comfortable walking this home/studio line.

Normally, engineers steer far clear of home audio equipment when it comes to monitoring. But producer Neal Pogue has been using the A’Diva speakers for just that, including five songs on the new Stevie Wonder album, and projects for Nelly Furtado, Indie Ari, Earth Wind and Fire, and Outkast. (See studioexpresso profile, or a 2004 interview in Electronic Musician for more about Pogue’s production background.) That’s pretty unusual for speakers aimed at the home market.

Having lived with a 2.1 set of the A’Diva Ti satellites for a while, I’m impressed, as well. The sound is uncolored and clear, with really gorgeous high-frequency definition. It makes these speakers sound both much larger than they are (you can fit them in your hand), and much more expensive. (They run just over US$200 a speaker, but you could easily fool someone into thinking they went for more.) That could make these ideal for complementing your existing set of monitors. I got to talk to Anthony Gallo, the speaker’s creator, about his background and, most importantly, why the speakers are spherical in the first place.

A’Divas on Test

First, if you’re like me, you’ve probably had some less-than-amazing experience with small speakers. There are plenty of small speakers that sound great at lower levels, but become harsh as you drive them. I was able to crank my A’Diva Ti setup to nearly painfully-loud levels without losing any clarity. It’s actually a little spooky: normally, “transparent” sound refers to the acoustic properties of speakers, but in the case of these two little spheres sitting on a shelf, there’s something unnerving about little tiny speakers making so much sound.

The drivers on the speakers are a combination of titanium and paper, hence the name and greater treble extension performance. There’s a 1″ voice coil for greater dynamic range, and to me, part of the reason these sound so good has to do with dynamic range and not just frequency range. I moved them around my living room studio and tried them both as traditional monitors and in a home stereo setup, and was pleased with the results for both. They’re small enough, as well, that you could easily mount them even in close quarters. Normally, that would allow you to set up a home theater, but it also happens to make them ideal as a secondary set of monitors for a studio.

The A’Diva Ti 2.1 setup I received for testing was mated with a 250-watt TR-2 subwoofer. Subwoofers are where home equipment tends to really reveal itself as a home product, but the TR-2 sounds terrific: rather than sounding boomy, it retains dynamic clarity right through the low end. (It’s good enough, in fact, that it revealed all kinds of nasty low-end mastering errors in my DVD collection, particularly with TV shows. Some disturbing up-mixing and down-mixing tends to happen when shows get tossed on DVD.) And, of course, those 250 watts are powerful in a way that’s incompatible with Manhattan living; after some brief fun in the middle of the afternoon, I decided I had to turn the level down as much as I could just to avoid getting evicted. (+6 dB boost? Uh, no, thanks, say the people on the fourth floor.) I think the 100-watt TR-1 would probably be fine if you’re in an 850 square-foot apartment. But if you want theater-sized bass and happen to live in the suburbs, you might look at the TR-2.

Just as with the satellites, the subwoofer eschews a rectangular design for a cylindrical enclosure. Unlike most subwoofers, the result feels well-crafted and looks quite lovely on its own. I was also pleased to find some decent options on the TR-2: low- and high-level I/O, plus EQ and a continuously-variable knob for phase.

Back to the original question, though: why am I bothering talking about “home theater” speakers on CDM in the first place? I can see a number of reasons why these would make sense. First, while I wouldn’t rely on them as my only studio monitors, they make a perfect second set, particularly when you want to experience what a 2.1 setup will do to your mix — but without the added coloration and, frankly, poor performance of a lot of inexpensive home speakers. Second, their size and shielding are perfect any time you need flexible placement. I’ve been looking for good speakers to use for installations, so I’m interested in them even for that. But when you’re in cramped quarters, even studio placement becomes an issue. Lastly, a lot of us have limited budgets and need speakers for our home setups. You want those to sound as good as your studio monitors, and you want them to be able to occasionally do double-duty. For me, at least, the A’Diva Ti’s fit the bill.

Now, I’m a fan of a very simple monitoring philosophy: listen in as many different ways as possible. I wish I still had my old Volvo 240 so I could try out mixes on its blown-out cassette and stereo system; if a mix worked there, it worked anywhere. “Mastering” is a pretty misleading concept because it suggests you know what people will listen on, when you don’t. So, I’m still going to hook up mixes — especially anything I’m considering for surround delivery — to some low-end setups, as well. But having the A’Diva setup to hear what’s going on across the frequency and dynamic range in more detail, and hear it the way it will sound in a 2.1 or 5.1 configuration, and have the setup for listening for enjoyment — that, to me, is the ideal.

I would never make a speaker recommendation blind (or is that deaf?); Gallo gets wide distribution so odds are you may have a set nearby you can go hear for yourself, and compare to some of the other available offerings. I will, however, stand by my feeling that you need more than one set of speakers to give your mix a good listening. And I’ll say, as well, more affordable surround setups like the Gallo could be just what we need to dip into surround, which has largely remained elusive to the home musician.

Of course, the one major downside of the A’Diva line is that they are configured as 2.1, which may rule them out as your primary monitors. Gallo is aware of this feedback, though, so perhaps we’ll see speakers geared for the studio in the future.

Conversation with Anthony Gallo

Anthony Gallo Acoustics really is the result of the designs of an engineer named Anthony Gallo. I always enjoy talking to the people who actually design the stuff, so I was pleased to get to talk to Anthony a bit about his background and the thinking behind his designs.

Anthony began building sound equipment early in his teenage years, designing speakers as young as 13. He told me that his early work with electrostatics had a big influence on his current designs. (He notes in the company history that he got a “shocked a zillion times.” Well, they are electrostatics, after all.) I’ve found most designers I’ve talked to got started with childhood tinkering, all the more reason to encourage Make Magazine-style experimentation in the next generation of young men and women.

A brief excerpt from our conversations:

Peter: It seems like there’s a resurgence of DIY electronics, after a long lull. Do you see more people becoming interested in DIY electronics?

Anthony: It’s harder to know if there are more DIY’ers out there today. It seems like there are because of the internet. You notice a lot more of them, but to say it’s a trend I’m really not sure. I’m glad to see there are a lot of people out there that have the same passion as I do.

Peter: Did those early experiments impact your work today?

Yes it does. However, when I was experimenting on my own over 20 years ago I didn’t have the resources to develop drivers or even enclosures that I knew in my heart would sound much better than wood. Such as utlra-rigid spherical structures and enclosures with curves. They are inherently much more rigid.

Peter: There’s a lot of confusion, it seems, about speaker wire. I know you sell your own wire for your speakers. What kinds of differences do you hear between different speaker wire; what differentiates yours?

Anthony: For every person you ask, everyone will have a different opinion on the sound of wire. I have selected a wire that is cost-effective and sounds excellent with our products. And in general, I tend to like solid core wire, rather than a lot of the stranded alternatives.

Depending on the type of wire, it could range from a grungy, bloated sound quality, to a crisp, clear transparent on the other extreme. And then there is every variation in between.

Peter: For the layperson, why spheres? And can you talk about how you personally came across spherical cabinets?

Anthony: Firstly, it is the lowest coincidence of external diffraction. External diffraction is what occurs when sound leaves the driver and wraps itself around the enclosure. If there are sharp projections, such as edges on a box speaker, it will interfere with the propagation of the driver and projects different frequencies. Also, the sphere is the most rigid enclosure and since it’s so rigid, the wall can be made very thin, which saves internal air volume and allows the speaker to be smaller than wooden/plastic boxes.

I read about it back in the 70’s, however it’s been well documented as early as the 30’s, that the sphere is the optimal shape for sound. (See attached the graph with frequency response for various enclosure shapes). Since I discovered this, I started seeking out hollow round structures that could be used.

Finding this graph in a textbook was an “ah-hah” moment in his own designs, Anthony says.

I know some readers here build their own loudspeakers, so I’ll be curious to see your own non-commercial designs, as well — and if we now have Anthony as a CDM reader, you can share them with someone who’s well-known in the business!

We’ll keep an eye on the new designs coming from Gallo in the future, as it sounds as though they’ve become more interested in the audio/music production market as well as home theaters. In the meantime, as usual, I expect there are many of you who know more about this than I do, so we welcome comments as always.
