Full Range, 6-element Premium

invisible speaker

The Stealth Acoustics model LR4G is a two panel, in-wall or in ceiling speaker that becomes completely invisible after installation. The paintable active diaphragm face is bonded to the frame of the speaker panel, creating an active area surrounded by a stable mounting perimeter. This model utilizes a separate panel for the low frequency driver to maximize clarity and reduce intermodulation distortion.

The LR4G incorporates four direct-to-fiber neodymium midrange motors and one direct-to-fiber neodymium high-frequency motor aligned in the new Stealth Quad-Balanced Midrange Drive configuration. Advanced internal carbon fiber materials allow for smooth frequency extension to 20 kHz. When the LR4G is installed in standard insulated 2″ x 4″ framing and allowed to function in a full 8 foot stud bay, frequence response below 45 Hz can be achieved with the separate low frequency panel.

The LR4G contains three independant protection circuits (low, mid-range and high frequency sections) that automatically reset upon reduction of excessive amplifier power.

The LR4G 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.
