If you've ever walked into a high-end audio shop and spotted a shiny metal ball sitting on a shelf, you've likely encountered a speaker Anthony Gallo had a hand in creating. Most people are used to speakers being big, heavy wooden boxes that take up way too much space in the living room, but Gallo decided pretty early on that the "box" was actually the enemy of good sound.
He didn't just want to make something that looked cool; he wanted to solve a specific physics problem. When you put a driver inside a square box, the sound waves bounce around inside and create all sorts of resonance and interference. By choosing a sphere, he basically eliminated those internal standing waves. It's one of those rare moments in design where the thing that looks the most "designer" is actually the most functional choice you could make.
Breaking the Mold with Spheres
Let's be honest, most of us buy speakers based on two things: how they look in our house and how they make our favorite albums sound. A speaker Anthony Gallo designed usually wins on both fronts. The spherical shape isn't just a gimmick. Because there are no flat parallel surfaces, the cabinet doesn't "color" the sound. You get this incredibly pure, transparent output that makes it feel like the singer is standing right in front of you.
I remember the first time I heard a pair of the original Micros. I couldn't believe that much sound was coming out of something the size of an orange. Usually, when you get speakers that small, they sound "tinny" or thin. But because Gallo used high-quality materials—we're talking steel and solid metals rather than cheap plastic—they had a weight and a punch that defied their size.
That Famous CDT Tweeter
You can't really talk about his work without mentioning the Cylindrical Diaphragm Transducer, or CDT. Most tweeters are little domes that move back and forth. The CDT is a different beast entirely. It's a flexible membrane that expands and contracts, giving you a 180-degree horizontal dispersion.
What does that mean for you when you're sitting on your couch? It means the "sweet spot" is huge. With traditional speakers, if you move six inches to the left, the high-end frequencies might start to drop off. With a speaker Anthony Gallo built using CDT technology, you can pretty much sit anywhere in the room and still get that crisp, detailed imaging. It's a game-changer for people who don't want to sit perfectly still in one chair just to enjoy their music.
The Micro and A'Diva Series
If you're looking to get into this brand, you're probably looking at the Micro or the A'Diva. These are the "bread and butter" of the lineup. The Micro is the 4-inch sphere that started the revolution. It's tiny, it's cute, and it comes in a million different colors.
The A'Diva is slightly larger—about 5 inches—and that extra internal volume gives it a bit more "oomph" in the lower mids. If you're setting up a home theater and you don't want giant towers flanking your TV, a few A'Divas mounted on the wall or ceiling are a brilliant way to go. They disappear into the decor but sound massive once the movie starts.
One thing to keep in mind, though: because these speakers are small, they aren't going to shake your floor with bass on their own. They're designed to work as part of a system. You'll definitely want to pair them with a decent subwoofer to fill in those low notes. Gallo actually made some pretty unique "drum" shaped subwoofers (like the TR-3D) that look just as funky as the speakers themselves.
Why Metal Cabinets Matter
Most speaker companies use MDF (medium-density fiberboard) because it's cheap and easy to work with. But a speaker Anthony Gallo produces is almost always made of metal. Why? Because metal is much stronger than wood at thinner dimensions.
This allows the speaker to have more internal air volume for its size. If you made a wooden speaker the same size as a Gallo Micro, the walls would have to be so thick that there wouldn't be any room left for the air to move. By using a thin, rigid metal shell, he squeezed every last drop of performance out of a tiny footprint. Plus, let's face it—a powder-coated stainless steel speaker looks a lot more premium than a vinyl-wrapped particle board box.
Living with Gallo Speakers Long-Term
I've talked to a lot of audiophiles who started with massive floor-standers and eventually "downsized" to a Gallo system. Often, it's because they moved into a smaller place or their partner got tired of the "monoliths" in the living room. The funny thing is, they usually don't feel like they've lost anything in terms of quality.
Setting them up is a bit of a different experience. Because they're spheres, they don't just sit on a flat shelf easily without their little rubber rings or specialized stands. But once you have them positioned, they stay out of the way. You can mount them on the wall, hang them from the ceiling, or put them on floor stands that look like modern art.
They're also incredibly durable. Since there's no wood to warp or veneer to peel, a speaker Anthony Gallo made twenty years ago usually looks just as good today as it did when it came out of the box. You might need to blow some dust off the drivers, but the build quality is basically tank-like.
The S-3 Centrifuge and Higher-End Gear
While the Micros get all the love for being small and affordable, Gallo also dipped his toes into some seriously high-end territory. The Reference series—like the 3.1 or 3.5—were legendary in the audiophile world. They looked like something off a spaceship, with multiple spheres stacked on a metal spine and that big CDT tweeter right in the middle.
These speakers proved that the spherical design wasn't just for "lifestyle" audio. They could compete with the $10,000 "audiophile" towers and, in many cases, beat them on imaging and clarity. It's a shame they're harder to find these days, but if you ever see a pair on the used market, jump on them. They are a masterclass in acoustic engineering.
Making the Choice
If you're on the fence about whether a speaker Anthony Gallo designed is right for you, think about your priorities. If you want a speaker that sounds "warm" and "vintage," these might be a bit too honest for you. They are transparent. They tell you exactly what's on the recording, for better or worse.
But if you value clarity, incredible 3D imaging, and a design that doesn't make your house look like a recording studio from 1974, they are hard to beat. They represent a time when speaker design actually took a leap forward instead of just putting the same old drivers in a slightly different shaped box.
Whether you're building a sleek 5.1 surround system for your basement or just want a pair of high-quality desktop speakers for your office, there's something about the Gallo sound that just sticks with you. It's clean, it's modern, and honestly, it's just a lot of fun to listen to. In a world of boring black boxes, the man with the silver spheres definitely knew what he was doing.
