The CW180R/CW180S provides a high performance in-wall CustomSound 

solution for in-ceiling and space restricted installations. Clever engineering 

and world-class industrial design combine in the PSB CW180 coaxial in-wall 

loudspeakers. Special attention has been paid to the issue of aiming sonic 

energy toward the listener without forfeiting sonic integrity. Available 

in round or square versions (CW180R and CW180S) each employ the same 

Platinum-derived eight-inch woofer and dome t weeter as the CW383, re-

engineered for a t wo-way layout. The PSB coaxial in-walls use a unique high 

frequency, constant directivity SonicGuide™ that is gimbaled to angle in 

any direction. The SonicGuide™ is a proprietary extensively adjustable and 

aimable, multipart fl are attached to a 1” metal dome t weeter. Its contours 

and dimensions are designed such that it provides very even response with 

little variation both on and off axis. It also increases the directivity of 

the t weeter so that the listener hears transparent, naturally focused 

sound. Equally important, SonicGuide reduces “backwards” t weeter energy 

that otherwise refl ects from the woofer cone, thus eliminating a serious 

response error that plagues virtually every other “coax” speaker. The 

SonicGuide can be tilted 30 degrees left or right and the whole assembly 

turned through 90 degrees. 

“Dog leg” style mounting clips insure quick and easy mounting. Two response 

tailoring switches provide adjustment to midrange and t weeter levels. 

Whether mounted in the wall or in the ceiling the system’s response can 

be directed toward the listener for best possible sound. The result is very 

natural sound quality and great installation versatility.
