Full Range, 2-Way Invisible In-Wall or In-Ceiling Speaker

The Stealth Acoustics model LR6G is a 2-way, full-range speaker 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. 

The Stealth Acoustics LR6G incorporates an acoustically coupled, high-power 6.5” cone woofer and a direct coupled 30 mm neo-magnet high-frequency motor. Advanced internal carbon fiber materials allow for smooth frequency extension to 20kHz. When the LR6G is installed in standard insulated 2” x 4” framing and allowed to function in a full 8 foot stud bay, frequency response below 45Hz can be achieved. The LR6G contains two independent protection circuits (high-frequency and low-frequency sections) that automatically reset upon reduction of excessive amplifier power.

The LR6G 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.
