For custom installations specifying in-wall subwoofers, PSB 
engineered the CustomSound CWS8. Evaluating the in-wall 
environment, PSB developed a subwoofer design that works well 
with the limited volume each wall presents and the typically less-
than-rigid wall construction. It features high excursion, high power 
handling dual eight-inch woofers with woven fi berglass cones for the 
output levels that movie lovers demand. “Dog leg” style mounting 
clips insure quick and easy mounting. The CWS8 subwoofer shares 
its mounting frame and dimensions with the PSB companion model 
CW383 8” 3-way in-wall system. As such they create ideal partners 
for the ultimate in full range in-wall sound reproduction. 
The CWS8 employs carefully engineered driver mass and 
motor-strength to “take the wall out of the equation,” delivering 
astonishingly powerful but controlled deep bass from a four-inch-
deep in-wall, for prodigious extension without stress or distortion, 
preserving the low-end “slam” critical to high-end home-theater bass.
The CWA-1 power amplifi er was designed for use with the 
CustomSound Series CWS8 and other passive subwoofers. The 
CWA-1 is a shelf mountable amplifi er, stable down to 2 ohms, with 
continuous power output of 300 watts. The CWA-1 features a full 
complement of subwoofer controls, such as variable low pass fi lter, 
phase switching, low frequency level, two different EQ/extension 
settings and a high pass output.  The 2-position EQ will allow the 
CWA-1 to suit the CWS8 and other future custom subwoofers, both 
large and small.  A unique feature of the CWA-1 is the parametric 
equalizer, which can be customized to correct undesirable 
resonances of the typical listening room. Full adjustment for 
bandwidth, center frequency and equalizer boost or cut is provided. 
Custom installers will appreciate the selectable music and voltage 
sensor triggering, input and output triggers plus built-in, automatic 
resetting overdrive current protection circuitry.
