Invisible Subwoofer

 

The Stealth Acoustics model B22G is a compact, two-panel monaural subwoofer speaker system that becomes completely invisible after installation. The subwoofer has a heavy duty rigid frame that attaches directly to standard structural framing. The paintable active diaphragm face is bonded to the frame of the speaker panel, creating an active area surrounded by a stable mounting area.  Each panel incorporates an acoustically coupled, high-quality, high-power 8” (203 mm) cone woofer.

 

Stealth Acoustics recommends the companion Model SA255 250-watt subwoofer amplifier/crossover as a matched amplifier for the B22G subwoofer speakers. Stealth Acoustics also offers a line of full-range speaker panels that when combined with the B22G, deliver a complete, totally invisible audio solution.

 

The B22G may be installed in either the wall or ceiling.  It can be finished on site with latex paint, light wallpaper, fabrics and selected texture coats. There is no need for special vellums or other nonstandard wallboard finishing materials. Advanced finishing methods such as Venetian plaster and select veneers are supported using special techniques.
