Stealth Acoustics B30g Pair
Brand Stealth Acoustics
**THE INSTALLATION BRACKET WHICH SUITS THESE SPEAKERS IS ONLY COMPATIBLE WITH LR3G AND B30G SPEAKERS**
The Stealth Acoustics Model B30G is a 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 B30G 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 may be supported using special techniques.
Ideal for any surround sound, foreground music or whole-house audio system that needs extra bass output, each B30G panel incorporates two acoustically coupled, high-quality, high-power 8” (203 mm) cone woofers. 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. B30G 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 B30G provides exceptional bass output from 20Hz to 160Hz by trading off excursion for surface area to propagate bass waveforms. Each panel has 331 sq. in. (840 sq. cm) of active area for a total of 662 sq. in. (1680 sq. cm) for both panels – nearly twice that of a typical 12” (304 mm) woofer.
Stealth Acoustics recommends the companion Model 255R 250-watt subwoofer amplifier/crossover as a matched amplifier for the B30G subwoofer speakers. Stealth Acoustics also offers a line of full-range speaker panels that when combined with the B30G, deliver a complete, totally invisible audio solution.
