Features and Benefits

Injection Molded TCC
(Talc, Carbon and Ceramic)
Woofer with Butyl Rubber
Surround and Vented Pole Piece
The Niles PSW8 Subwoofer employs a
newly developed cone material that com-
bines injection molded polypropylene
with talc, carbon and ceramic stiffening
agents. The result is a cone that offers
extreme stiffness and light weight for accu-
rate, dynamic response. Additionally, the
woofer employs a vented pole piece for
increased bass linearity and a Butyl
Rubber Surround for improved damping
and clarity as well as moisture resistance.

Inverted Dust Cap
The inverted dust cap feature of the PSW8
actually reinforces the cone to further
increase the stiffness-to-mass ratio and
reduce distortion. In a subwoofer applica-
tion, this dust cap inversion offers the addi-
tional benefit of reducing the "oil can" effect
that can cause traditional woofers to pro-
duce unwanted high frequency overtones.
Antiresonant Wave Bracing
The HD speaker's baffle design employs
specially molded ribs that increase the
rigidity of the baffle and raise the resonant
frequency so that less "out-of-phase" can-
cellation takes place. Equally important,
the ribs are curved and crossed to further
shift vibration modes away from low-bass
canceling frequencies. This keeps bass
tones rich and dynamic.

The PSW8 In-wall subwoofer
includes an easy access, baffle
mounted high-pass filter to prevent
over-excursion of the satellite's
woofers. It also has an easy
access, baffle mounted low-pass
frequency selection switch.
