Inputs and Outputs Notes
Driver: The PSW303 uses an
8" high excursion polymer composite cone driver for deep, smooth
response and low distortion. For improved durability, the woofer uses a hi-roll foam
Video Shielded: The subwoofer
is magnetically shielded to allow safe placement next to TVs and video monitors.
Amplifier: The subwoofer is
powered by a high-current amplifier producing 100 watts RMS/260 watts dynamic
PSW303's solid MDF enclosure (including a one inch thick front baffle)
suppresses enclosure panel resonance for distortion-free, accurate response.
Venting: The PSW303
features a wide, long, slot-load vent (approximately 8-3/8" x 7/8") to
dramatically reduce turbulence, noise and distortion and significantly improve
3-Way Power Switch: The
subwoofer has a 3-way power switch on the rear panel. You can select
"Auto", which turns the unit on automatically when an input signal is
received and off a few minutes after the signal stops; "On"
which keeps the unit on until it is switched off, and "Off" which
turns the unit completely off (instead of placing it in a standby mode). The LED
power indicator glows green when the unit is on and red when the unit is off.
Control: The PSW303 has
a rotary volume control to adjust the volume of the subwoofer relative to the
other speakers in the system.
The subwoofer's phase
switch allows you to select normal or reverse. If the bass sounds muddy or
unclear, toggling the phase control can sometimes strengthen the bass
Filter: The PSW303 offers a continuously variable low-pass filter, adjustable from
60-160Hz with a 24dB/octave slope. Note:
When the subwoofer is connected to a receiver through the LFE input, the low-pass filter of the subwoofer is bypassed. The filter
built into the receiver is relied upon to filter the subwoofer output
System: The PSW303 powered subwoofer perfectly compliments Polk Audio's
RM6700 (or other RM-series)
Home Theater speaker package. The RM6700 package, consisting of 4 identical
front and rear satellites and a matching center channel speaker is available in
black or titanium finish.
and Outputs Notes LFE
(Unfiltered) Input: The PSW303
has a gold-plated mono RCA LFE (Low Frequency Effects) input. This input should
be used when connecting to a receiver with a filtered subwoofer output (check
the receiver's owner's manual). The LFE input bypasses the subwoofer's built-in
low pass crossover. Note: If the receiver's subwoofer output is
unfiltered, you should use either the left or right Line Input of the subwoofer.
The subwoofer has gold plated left and
right RCA Line
Level inputs. These inputs are for use with
electronics featuring unfiltered "Pre Out" jacks (Example: a separate
pre-amp processor with a separate amplifier). It may require "Y
adapters" to connect the left and right outputs of the pre-amp processor to
both the subwoofer and the power amplifier.
Level Input/Output: The
subwoofer has spring clip connections for front speaker level input and output.
The subwoofer's low-pass filter takes the low frequencies (based on the setting
of the filter) and passes a full-range signal out to the speakers. This is
the recommended method of connecting the subwoofer with a Polk Audio RM-series
Home Theater speaker package and other "satellite" speaker systems.
Response: The overall frequency response for the subwoofer is
-3 dB frequency response is 35-160Hz.
The PSW303 weighs 27 pounds.
Amplifier: The warranty on the
amplifier is 3 years parts and labor.
Driver: The warranty on the
driver is 5 years parts and labor.
