2 CSW SERIES LOUDSPEAKERS
CSW CUSTOM BUILT-IN HIGH
PERFORMANCE SUBWOOFERS
These are the built-in subwoofers and dedicated
power amplifier for custom home installations that
will raise the roof beams with their performance as
they tuck out of sight to blend with any architectural
style or interior design. If you’re looking for tight,
musical bass, you’ve found your subwoofers.
CSW SUBWOOFERS COMBINE ULTRA-
PERFORMANCE WITH ULTRA-RELIABILITY
The subwoofers’ long-throw designs have been thought
out with not only big, robust performance in mind, but
ultra-reliability, too. Massive motor structures, each
employing a tall coil, have been Klippel laser -optimized
to perfectly position the voice coil in the magnetic gap,
helping ensure a linear excursion of 25mm peak to peak.
The CSW100 and CSW200, as well as the CSW155, use
dual spiders for symmetric excursion stiffness. The overall
result is tight, superbly detailed, lower distortion bass.
CSW155
AN IN-W ALL THAT ACTUALLY
OUTPERFORMS MANY FREESTANDING
POWERED SUBWOOFERS
The CSW155 is for anyone who covets uncompromising
bass performance in a nearly invisible package. The CSW155’s
single 10" diameter driver is the shallowest ever engineered
by Polk, ensuring the CSW155 fits easily in a wall. This is
really big bass that’s created with ultra-reliability in mind.
A massive 2" voice coil for high output and power handling,
plus dual spiders that ensure linear excursion and prevent
bottoming out are just some of the features that ensure
ultimate performance and reliability. A 15 1/2" x 17 1/2"
perforated grille that mimics the look of an air register is
included with the CSW155. The CSW155 stands 60" tall
but fits comfortably between standard 16" on-center studs.
