The Stealth Acoustics Model B22G is a compact, two-panel monaural subwoofer speaker system that becomes completely invisible after installation. The subwoofer has a 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. Installation instructions are shown on a paper overlay that is to be removed before installation. The overlay can also be used as a cutting template for retrofitting the speakers into existing wallboard.

The B22G may be installed in either the wall or ceiling and on-site finishing options include latex paint, light wallpaper, fabrics and selected texture coats. There is no need for nonstandard wallboard finishing materials. Advanced finishing methods may be supported using special techniques.

Ideal for any surround sound, foreground music or whole-house audio system that needs extra bass output, each B22G panel incorporates an acoustically coupled, high-quality, high-power 8” (203 mm) cone woofer. The panels work in pairs as a monaural output subwoofer. This two-panel system allows each panel to be placed wherever they perform best, free of visual concerns that may conflict with architectural features. B22G panels may be mounted separately or stacked to achieve desired acoustical results. For stereo subwoofers, four panels should be employed.

Using acoustic lever principals, the B22G provides exceptional bass output from 30Hz to 150Hz by trading off excursion for surface area to propagate bass waveforms. Each panel has 228 sq. in. (579 sq. cm) of active area for a total of 456 sq. in. (1158 sq. cm) for both panels.
