PSB Speakers CWA-1, CWS8 dimensions

Be He ard, Not Seen

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.
