ACOUSTICS LR3g

3 WAY
TOTALLY INVISIBLE IN-WALL OR IN-CEILING LOUDSPEAKERS (pair)

The Stealth Acoustics Model
LR3G 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 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 non- standard
wallboard finishing materials. Advanced finishing methods may be supported
using special techniques.

The Stealth Acoustics LR3G incorporates an acoustically coupled high quality, high-
power 8” cone woofer and direct 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 40 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.

For proper registration,
each speaker must be installed so that the surface of the perimeter edge is
flush with the adjoining wallboard. When correctly in place, the surface of
the speaker face panel extends above the height of the wallboard by
1/16” (1.6 mm). This is done to allow space for the tape and joint compound
needed to blend the panel into the wall. Shims are included to allow for
mounting in wallboard thicker than 1/2” (9.5 mm).

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. Accompanying
the full range panels, Stealth Acoustics offers the B22G and B30G
– completely invisible companion
subwoofers for extended low frequency response.

All Stealth Acoustics
products are covered by a 5 year manufacturer’s warranty as well as an optional
15 year extended warranty. The LR3G also
has 100, 70 and 25 volt constant voltage transformers available as factory
installed options.

Architectural &
Engineering Specifications

The loudspeaker shall be a
two-way, full-range device, produc- ing frequencies from 40Hz to 20kHz. The
total radiating surface shall be 480 sq. in (3097 sq. cm) and high frequency
dispersion shall be a nominal 170 degrees in both horizontal and vertical
planes. The loudspeaker system shall have a sensitivity of 83 dB, 1 watt / 1
meter, with a capacity of 200 watts RMS accord- ing to EIA standard RS-426-A.
The loudspeaker shall have three independent self-resetting protection devices,
one each for the high-frequency, midrange, and low-frequency drivers

The loudspeaker shall fit
into walls and ceilings with wood or steel stud construction and a standard
2-1/2” (63.5 mm) depth cavity. The loudspeaker shall mount directly to the
structural framing and have the capability of seamlessly adjoining 1/2” (9.5
mm) or thicker gypsum wallboard. The minimum distance between framing members
shall be 9-1/2” (241 mm). Face panel finishing methods shall be consistent with
normal gypsum wallboard finishing techniques and may include latex paint, light
wallpaper, light fabric and other selected approved finishes.
