In-wall loudspeakers must deal with limited space within the confi nes 

behind the wall along with generally fl imsy wall construction. 

Enclosure volume plays a large part in facilitating bass performance. 

With suffi cient available volume the system can naturally extend to 

lower frequencies, and offer greater sensitivity.  Wall cavities are not 

built to any standard volume so open back in-wall speakers must 

work within a wide range of wall cavity volumes.  PSB accomplishes 

this by giving the woofers higher mass and stiffness than with 

conventional “in room” enclosures.  Extensive simulations and 

testing have shown that our designs deliver high-performance sound 

quality with a broad range of wall cavity volumes.  

The CW383 is a sophisticated 3-way in-wall system. The system 

is constructed on a rigid precision molded baffl e. The eight-inch 

woofer with woven fi berglass cone ensures high power handling 

and extended bandwidth. A high performance four-inch enclosed 

midrange with woven fi berglass cone and a swivel 1” aluminum 

dome tweeter complete the driver complement. The midrange/

tweeter array can be rotated in 90 degree increments for best on and 

off axis response, no matter what the system orientation. Response 

is always best when the midrange and tweeter are vertically arrayed, 

but since the system can be mounted horizontally or vertically, 

rotation of the midrange/tweeter baffl e assures that optimum 

conditions are met. Furthermore, the tweeter can be pivoted in its 

mounting to aim it toward the listener.  “Dog leg” style mounting clips 

insure quick and easy mounting. Two response tailoring switches 

give adjustment to midrange and tweeter levels or to compensate 

for placement behind perforated screens. The CW383 shares its 

mounting frame and dimensions with the PSB companion model 

CWS8 subwoofer. As such they create ideal partners for the ultimate 

in full range in-wall sound reproduction.
