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.
Phase Switch: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 NotesLFE
(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.
Inputs: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.
Weight: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.
