The Stealth Acoustics Model L-RAD 430 is a three-way, full-range loudspeaker system that becomes completely invisible after installation. The loudspeaker 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 L-RAD 430 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.

The Stealth Acoustics L-RAD 430 incorporates an acoustically coupled high quality, low profile, high-power 8" cone woofer, a 30 mm direct coupled neomagnet mid-range driver, a direct coupled 25 mm neo-magnet high-frequency driver, and an acoustically tuned back box. Advanced internal materials allow for smooth frequency extension to 20kHz. When the L-RAD 430 is installed in standard insulated 2" × 4" framing and allowed to function in a full 8 foot stud bay, frequency response below 35Hz can be achieved. The L-RAD 430 contains two independent protection circuits (high/ mid- and low-frequency sections) that automatically reset upon reduction of excessive amplifier power.

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 ½" (13 mm).

Stealth Acoustics’ invisibility offers a powerful advantage over traditional loudspeakers because they can be placed wherever they sound best, free of visual concerns that may conflict with architectural features. Accompanying the full range panels, Stealth Acoustics offers completely invisible companion subwoofers for extended low frequency response. All Stealth Acoustics speakers are covered by a 20-year manufacturer’s warranty.
