CW180R / CW180S 8” Coaxial Speaker System

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 tweeter as the

CW383, re-engineered for a two-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 tweeter. 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

tweeter so that the listener hears transparent, naturally focused

sound. Equally important, SonicGuide reduces “backwards” tweeter

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 tweeter 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.

Installation Notes

• Optimum installation height (CW180S) is
between seated and standing ear level
position.

• Distance between left and right speakers
(CW180S/R) should approximately equal the
distance from the listening area to the wall or
ceiling.

• Make small exploratory hole and check for
obstructions in wall cavity before cutting
mounting hole.

• Mounting template provided.

• Lightly fi ll wall cavity with fi berglass 2 feet
above and below system (CW180S). Use
standard 4” fi berglass split to half thickness.
Use 1” thick fi berglass behind system.

• Adjust electric screwdrivers to appropriate
torque. Tighten 4 mounting screws fi rmly but
do not over tighten!

• SonicGuide tweeter can be turned +- 45
degrees via the gimbal ring, then +- 30
degrees on its axis (see illustration on left).

• Aim tweeter toward center of listening area
via SonicGuide and gimbal ring.

• Switches give subtle balance adjustments
for midrange and treble. Set to suit room
acoustics and personal taste.

• See manual for more installation hints.
