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.
Overview: The CW28 from PSB Speakers is a pair of
high-performance wall-mount speakers. The CustomSound CW Series of
in-wall/in-ceiling speakers incorporate the same speaker arrays as found in
PSB's highly acclaimed Platinum-series speakers for true audiophile performance.
Drivers: The CW28 speakers employ an 8"
fiberglass-textured polypropylene woofer, which has a higher cone mass and
enhanced motor strength for higher power handling. The rubber surround damps resonance and provides exceptional
durability. The low-resonance 1" aluminum dome tweeter delivers exceptional
clarity in the high frequencies. The tweeter has a pivoting mount, allowing it
to be aimed towards the listening area for best response.
Frequency Adjustment Switches: Because in-wall speakers are
surrounded by hard surfaces that reflect the sound output, it may be necessary
to adjust the high and midrange frequencies. The CW28 has two rotary switches
mounted on the front baffle that allow you to independently adjust the treble
and midrange frequencies by +/- 2dB. The switches can be adjusted using a
Frames: The white ABS plastic frames extend approximately
3/4" beyond the grilles on the finished side. The frames also extend about 5/8"
beyond the rough opening cutout. The speaker requires a 9-1/4" x 13-5/16" wall
cutout for mounting the speaker.
Grilles: The speakers are equipped with flush-mount aluminum grilles for a clean and unobtrusive look. The grilles have
hundreds of precisely-sized perforations to make them acoustically transparent.
The grilles and frames are paintable to match any decor.
Mounting Clamps: The CW28s have 6 toggle-style mounting
clamps for installing the speakers in the wall or ceiling. When a Phillips-head
screwdriver is first applied to the mounting screws, the clamps "toggle" out
from a rest position (out of the way for easy insertion), turning 90 degrees and
into a position to clamp firmly against the wall.
Pre-construction Bracket: For new construction, the optional
bracket (760CK28, sold separately) is recommended. The bracket is designed to be a
"hole-saver" to indicate where the speaker should be installed before the
drywall goes up. In addition, an optional BBX-88 Performance Enclosure
(available from the manufacturer) defines the optimal enclosure volume for the CustomSound series speakers, and mounts between two studs behind drywall.
Weather Resistant: The CW28 is weather resistant to
enable installation in moist environments, such as bathrooms or indoor pool
areas, or outdoors in porch ceilings or under eaves. The polypropylene cones
with rubber surrounds, stainless steel fasteners, aluminum grilles and ABS
can withstand moisture, but the back of the speaker should be protected. The
speakers should not be installed in an area that is totally exposed to the
