SA2B™
SA SOUND ADVANCE R
A TRULY INVISIBLE, EXTENDED BANDWIDTH, WIDE DISPERSION LOUDSPEAKER SYSTEM
The extraordinary SOUND ADVANCE SA2B is a two-way, full-range planar loudspeaker system designed for application in commercial
and residential installations.
Its proprietary structural and engineering features make it possible to invisibly install in almost any standard wood/metal stud wall or ceiling, essentially becoming an integral part of the wall or ceiling surface.
Because of the SA2B’s patented Planar Diaphragm Technology™, when properly installed in a wall or ceiling, the loudspeaker system will radiate in a smooth, even coverage hemispherical pattern with more than 140° of dispersion throughout its bandwidth.
The SOUND ADVANCE SA2B employs a flat rigid diaphragm, approximately onehalf inch thick, that installs into a standard wall cavity replacing the equivalent surface area of gypsumboard. The flat vellum overlay which is applied to the loudspeaker surface may be finished with water soluble materials such as latex paints, to match any color or decor requirement, using c o n v e n t i o n a l brush-on, roller, or airless spray appli-
cation systems. Additionally the SA2B may be covered using wallpaper, light weight vinyl wall coverings and selected textured coatings*.

The SA2B’s exclusive installation methods, including the use of matching surface treatments, uniquely allows the speaker to

be made truly invisible. This capability allows the loudspeaker system to be placed wherever optimal acoustics dictate, elimi-
nating any visual concerns.
The SA2B utilizes a mechanically derived crossover centered at 1 kHz with a 12 dB per octave slope for both low-frequency and high-frequency sections. Each loudspeaker contains two independent protection circuits (high-frequency and low-fre- quency) that automatically reset after an overload condition has been removed.

ENGINEERS
SPECIFICATION:
The aesthetic loudspeaker shall be a two-way, fullrange device, producing frequen-
cies from 70Hz to 20 kHz. Total radiating surface shall be 294.0 sq. in. (1896.0 sq. cm.) and high frequency dispersion shall be 140¡ to at least 20 kHz in both horizontal and vertical planes.
The loudspeaker system shall have a sensitivity of 90 dB, 1W/1M, with a power rating of 60 watts RMS as per EIA standard RS- 426-A. The loudspeaker shall have two independent self-resetting custom gel switch protection devices, for the high-frequency driver and the low-frequency driver.
The loudspeaker shall have an exterior frame constructed of extruded aluminum that is 21.0 in. (53.3 cm.) long by 14.0 in. (35.6 cm.) wide and 3.0 in. (7.6 cm.) in total unit depth - not including backbox. The loudspeaker shall fit into standard wall and ceiling construction and occupy an area of approximately 2.0 sq. ft. (0.19 sq. m.).
SOUND ADVANCE offers a range of backboxes to allow code/installation requirements to be met.
One (1) loudspeaker with normal mounting hardware shall weigh 7.7 lbs. (3.49 kg.).
The loudspeaker shall be the SOUND ADVANCE SYSTEMS SA2B or equivalent.
