Today we’re sharing a pic of a pair of 19hz tuned Devastators. This version is tuned for home theater use, and we also offer a 28hz (pro-audio) version. Over the years, the 19hz Devastator design has earned a reputation for delivering significant SPL capability from 20hz to100hz, that’s often described as highly tactile, accurate and appropriately face melting : )

Horn-loaded subwoofers are legendary for their efficiency, dynamics, and incredible mid-bass impact. The downside? Traditionally, they require enormous enclosures.

Enter the GSG G-Sub.

Designed to deliver the benefits of horn loading in a surprisingly manageable form factor, the G-Sub offers an exceptional combination of size, output, and low-frequency extension.

✅ Compact by horn standards — a space-conscious design that makes high-performance horn loading more practical for home theater installations.

✅ Outstanding mid-bass performance — tremendous punch, effortless dynamics, and the kind of tactile impact that brings movie soundtracks to life.

✅ Extension into the low 20Hz range — proving that a relatively compact horn design doesn’t have to sacrifice impressive low-frequency performance.

✅ High-impact home theater performance — engineered for enthusiasts who demand serious output and dynamic capability.

The G-Sub delivers a compelling balance of efficiency, mid-bass authority, low-frequency extension, and enclosure size.

Today GSG Audio Design has earned a reputation for offering some of the highest performing subwoofer systems in the United States, along with exceptional value, and best in class aesthetics.

Why you can’t stop buying subwoofers.

10/03/2026

Today we are sharing 4 fully finished sealed BTS series subwoofers headed to Josh G, in Los Angeles. Each subwoofer measures 22x22x17, and all 4 subs will be installed into a new dedicated theater room. The theater has a beautiful design, and we’ll be sure to post updated pics in the future. Our BTS series now has 22+ form factors, and we are now releasing a few new models which have depths in the 12-13 inch range (aka Waveforming absorber models built to preventing standing waves and reducing low-frequency decay times, or for dealers & consumers who simply need high performance subwoofers with shallow footprints).

Today we’re sharing another fully finished 46x29x17 BTS series Sealed 24 headed next week. Our BTS series of enclosures now includes 22 form factor options, guaranteeing great versatility.

Our team in Los Angeles can build active subwoofers (plate amp installed) or passive models (no plate amp installed, rack mount amp needed). We can also finish subwoofers in our low reflectivity/low texture black satin (pictured here), or our recently introduced high gloss options (black, red, white, blue, pearl options & custom color choice).

If you are customer or dealer considering working with us in 2026, we look forward to hearing from you. We’re a team of 7, all passionate about home theater & high-performance subwoofers, with a great reputation in the AV community.

Today we’re sharing our fully finished BTS series ported 24, headed to a theater in Florham Park NJ, owned by by Tim B.

Our BTS ported 24 measures 72x40x17, so it’s size isn’t going to work for many, and we’re just fine with that (we have 6 other sealed 24 form factors for them).

Customers who love the idea of a ported 24 at 10hz, will experience incredible SPL reproduction well into single digits, tightly controlled and accurate bass, and output under 20hz that would require multiple sealed 24s.

This impressive theater checks all the boxes — a massive Cinemascope screen, beautifully organized equipment rack, two rows of seating, and some serious bass hiding behind the screen.

For low-frequency duty, this customer chose two GSG BTS 28×48×17 ported enclosures, tuned to 19Hz, along with two of our port redirection kits to route the ports forward into the room.

The result? A clean installation with huge low-frequency capability — without sacrificing valuable theater space.

Our BTS Series continues to be one of the most popular choices for both GSG customers and our dealer partners, with configurations available for 15”, 18”, 21”, 24”, 32” drivers.

If you’re building a theater and demand high quality bass reproduction, the BTS lineup gives you a lot of ways to get there.
