The workhorse of Triad's custom subwoofer line has been dramatically improved. In an otherwise all-new subwoofer lineup, we have maintained the same excellent long-throw 10" driver and enclosure, but switched to the new RackAmp 350 DSP which delivers nearly 50% more power than its predecessor for even more output and headroom than before. The new DSP amps provide simple "plug-and-play," and EZ set-up. You can have great performance right out of the box in nearly any room.

Unlike most inwall subwoofers, the InWall Bronze/ Sub is a real performer. It is designed to fit into a 6" stud space, and it uses a handsome, flush Acoustimesh grill. And we build all Triad speakers to order, and offer custom paint matching to the paint sample or paint number that you supply.

The InWall Bronze/6 Sub may be used in multiples, each with its own amplifier, in home theater applications. Or, a single Bronze/6 may be used for a den, bedroom, guest room, family room, or office. At low listening levels or for background, an InWall Bronze/6 Sub adds fullness and warmth, and at higher levels, it adds dynamics and weight. Other versions include the InCeiling Bronze/10 Sub and the InWall Bronze/4 Sub.
