The Sound Advance®SA2C is a two-way, full-range planar loudspeaker system designed for use in commercial installations.
(For residential installations we recommend using the SA2 version, which is transformerless.) Proprietary structural and
engineering features make it possible to invisibly install the SA2C in almost any standard wood/metal stud wall or ceiling:
the speaker essentially becomes an integral part of the wall or ceiling surface. Patented Planar Diaphragm Technology™
allows SA2Cs that have been properly installed in a ceiling or wall boundary to radiate sound in a 140° hemispherical
pattern with smooth, even coverage throughout its bandwidth.
The Sound Advance SA2C employs a flat rigid diaphragm, approximately one-half inch thick, that installs into a standard wall
cavity replacing the equivalent surface area of gypsum board. The supplied flat vellum overlay which is applied to the loudspeaker surface during installation may be finished with water-soluble materials — such as latex paints — to match any color
or decor requirement, using conventional brush-on, roller, or airless spray application systems. Additionally, the SA2C may be
covered using wallpaper, light-weight vinyl wall coverings and selected textured coatings. (Please contact the factory before
applying any textured coating to Sound Advance products).
The SA2C’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, eliminating
any visual concerns. The SA2C utilizes a 12dB per octave crossover centered at 2kHz, with both low-pass and high-pass sections.
Each loudspeaker contains two independent protection circuits (high-frequency and low-frequency) that automatically reset
after an overload condition has been removed. The SA2C is transformer-coupled, with the following input taps: 0.5W, 1W,
2W, 4W, 8W, 16W, 32W and 4-ohm bypass.
