GSG was built by enthusiast for enthusiasts and we offer subwoofers with 12, 15, 18, 21, 24, and 32 inch drivers. If you are chasing better bass, we’re here for it….however far you want to take it.

Each subwoofer measures 28x28x22, and GSG now offers seven different 24 inch form factors (5 sealed, 1 ported, 1 dual opposed).

Today we’re sharing a theater room being built by our friend Jared K out of Sterling Heights MI.

In the front of his theater Jared is using two of our dual 24 sealed BTS subwoofers ( BTS = behind the screen). In the rear of the theater, are two more dual 21 BTS series subs. In total we’ve got 4 x 24s and 4 x 21’s handling low frequency reproduction, and it will be EPIC!

If you would like to learn more about Jared’s theater build, he’s got an excellent thread going on AVS forum, in the “Dedicated Theater Design & Construction” section.

Today we’re sharing a pair of BTS series 32x29x17 sealed 21’s, each using a Eminence NSW6021. The NSW6021 offers strong excursion, high sensitivity, power handling, and exceptional motor force.

Today we’re sharing some 24 inch subwoofer build pics, as they move through cutting, assembly, cabinet finish, woofer/feet install. The pictured model is our 32x29x17 BTS series, and its 17 inch depth makes it extremely versatile.
