3-WAY EXPERT GRADE INVISIBLE LOUDSPEAKER
The Stealth Acoustics model LRX-83 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 LRX-83 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 nonstandard wallboard finishing materials. Advanced finishing methods such as veneer treatments may be supported using special techniques.
The Stealth Acoustics LRX-83 incorporates an acoustically coupled high quality low profile, high-power 8” cone woofer, a 30mm direct coupled neo-magnet mid-range driver and a direct coupled 25 mm neo-magnet high-frequency driver. Advanced internal materials allow for smooth frequency extension to 20 kHz. When the LRX-83 is installed in the recommended back-box, frequency response below 40 Hz can be achieved. The LRX-83 contains two independent protection circuits (high/mid-frequency and low-frequency sections) that automatically reset upon reduction of excessive amplifier power.
