Stealth Model B22 Invisible Subwoofer System

Perfect for Full Range, Whole House Audio

The Stealth Acoustics Model B22 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 B22 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 special vellums or other nonstandard wallboard finishing materials. Advanced finishing methods such as Venetian plaster and select veneers are supported using special techniques.

Ideal for any surround sound, foreground music or whole-house audio system that needs extra bass output, each B22 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. B22 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 B22 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.

For proper registration, each speaker must be installed so that the surface of the perimeter edge is flush with the adjoining wallboard. When correctly in place, the surface of the speaker face panel extends above the height of the wallboard by 1/16" (1.6 mm). This is done to allow space for the tape and joint compound needed to blend the panel into the wall. Shims are included to allow for mounting in wallboard thicker than 3/8" (9.5 mm).

Stealth Acoustics recommends the companion Model 255R 250-watt subwoofer amplifier/crossover as a matched amplifier for the B22 subwoofer speakers. Stealth Acoustics also offers a line of full-range speaker panels and an 8-channel amplifier (Model 8400) that, when combined with the B22, delivers a complete, totally invisible audio solution.

All Stealth Acoustic products are covered by a 5-year manufacturer's warranty as well as an optional 15-year extended warranty.
