Full Range, Invisible In-Wall or In-Ceiling Speaker


The Stealth Acoustics model LR3G is a 3-way, full-range speaker system that becomes completely invisible after installation. The speaker 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.


The Stealth Acoustics LR3G incorporates an acoustically coupled high-power 8” cone woofer with 3 directly coupled 25 mm neo-magnet high-frequency motors. Advanced internal carbon fiber materials allow for smooth frequency extension to 20 kHz. When the LR3G is installed in standard insulated 2” x 4” framing and allowed to function in a full 8 foot stud bay, frequency response below 45 Hz can be achieved. The LR3G contains three independent protection circuits (low, mid-range and high frequency sections) that automatically reset upon reduction of excessive amplifier power.


The LR3G 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.
