LRX85

FULL RANGE 7-ELEMENT EXPERT-GRADE HIGH-POWER 2 PANEL INVISIBLE SPEAKER SYSTEM

The model LRX-85 invisible speaker is a premium, 3-way, two panel system The LRX-85 is truly a powerful and complete full-range solution, requiring no special bass-limiting filters, ancillary protection circuits or external subwoofers. For even greater ability, an active, bi-amplified
LRX-85ACT version is also available.

300watt power handling enables output up to 105dB with premium extendedrange sound quality. The LRX-85 performs as an exemplary invisible speaker in a wide range of applications, including home theaters, high-impact distributed audio and critical listening environments where aesthetic needs demand no visible presence of a loudspeaker.

The LRX85 utilizes separate, easy to install, flat front panels for mid-high and bass reproduction, improving performance while minimizing intermodulation distortion. The two panels may be mounted as far a 1meter apart and still provide quality outcomes.

The mid-high panel incorporates four 25watt neodymium midrange motors and one 25watt neodymium high-frequency motor aligned in Stealth’s Quad-Balanced Midrange Drive™ configuration. Advanced internal materials and smooth sounding FidelityGlass™ panel face allow for upper frequency response to 20 kHz. A multi-stage passive crossover is provided to allow a single speaker line from the amplifier to feed both mid-high and bass panels. The LRX-85 crossover contains three independent self-resetting protection circuits to protect the speaker from excessive amplifier power, ensuring maximum long-term reliability.

The separate dual 8” high-power cone woofer bass-stage panel provides extended bass response down to 35Hz when the panel is installed in a
recommended back box and properly tuned. The result is an impressive sounding loudspeaker rivaling visible alternatives.

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. The LRX-85 is designed to be installed into standard wall or ceiling constructions with many on-site finishing options that include paint, light wallpaper, fabrics, wood veneers, vinyl graphics and selected texture coats. There is no need for non-standard wallboard finishing materials. 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. Unique mounting and advanced finishing methods may be accomplished using special techniques.
