Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Coaxial Speaker Design: The PSB CW180R high-performance
square in-ceiling speaker utilizes a coaxial driver design with a 1" metal
dome tweeter mated to a 8" polypropylene cone woofer. Coaxial speakers are
very popular due to their small footprint making them ideal for space restricted
SonicGuide: The PSB CW180R in-ceiling speaker uses a unique
high frequency, constant directivity SonicGuide. The SonicGuide is a proprietary
extensively adjustable and aimable, multipart flare attached to the in-ceiling
speaker's 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, the SonicGuide reduces
"backwards" tweeter energy that otherwise reflects from the woofer cone, thus
eliminating a serious response error that plagues virtually every other "coax"
speaker. The SonicGuide can be tilted 30°
left or right.
Treble/Midrange Level Switches: Two response tailoring
switches provide a 3dB adjustment to midrange and tweeter levels.
Basket/Frame: The CW180R has a sturdy ABS basket and frame.
The frame can be painted to match any decor (a clear paint mask is supplied to
protect the drivers from overspray). The aluminum mesh grille is also paintable.
Speaker Terminals: The PSB CW180R in-ceiling speaker is
fitted with spring-load post speaker terminals to connect your in-ceiling
speaker wire. The spring-post terminals will accept bare wire (up to 12AWG),
pin-connectors, and banana plugs (single or dual).
Mounting Options: The PSB CW180R uses an effective mounting
technique with toggle-style mounting clamps. These four "dog-leg" style mounting
clips insure quick, easy, and secure mounting in the ceiling. A template is
provided for marking the speaker cutout. It has a series of slots for tracing
the cutout and also an outline of the speaker to confirm that the flange won't
interfere with any ceiling features. The CW180R requires a cut-out diameter of
9.875" with a mounting dept of 4.0625". There needs to be at least 0.6875" of
space around the cut-out to accommodate the in-ceiling speaker's overall frame.
The speaker's frame and grille will sit 0.75" away from the ceiling.
Note: For the new construction application, PSB offers
Performance Enclosure and Preconstruction Bracket solutions (both sold
separately by manufacture). The Performance Enclosure provides optimal low
frequency response and is mounted between two studs behind drywall. The
Pre-construction Brackets simplify installation in new construction
application and can be used with or without the Performance Enclosure.
