Inputs and Outputs Notes
Driver: The PSW505
uses a 12" long-throw polymer composite cone driver for deep, smooth
response and low distortion. For longer excursion, the woofer uses a hi-roll
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 300 watts RMS/460 watts dynamic
PSW505's solid MDF enclosure (including a one inch thick front baffle)
suppresses enclosure panel resonance for distortion-free, accurate response.
Venting: The PSW505
features a wide, long, rear-firing slot-load vent (approximately 12" x 1-1/4") 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 PSW505 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 PSW505
offers a continuously variable low-pass filter, adjustable from 60-120Hz with a
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 frequencies.
and Outputs NotesLFE
(Unfiltered) Input: The
PSW505 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,
such as those found on most home theater receivers (check the receiver's owner's
manual). The LFE input bypasses the subwoofer's built-in low pass crossover.
the receiver's subwoofer output is unfiltered, you should use either the
left or right Line Input of the subwoofer.
(Filtered) 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
5-way binding post 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 23-160Hz,
and the -3 dB frequency response is 28-125Hz.
Amplifier: The warranty on the
amplifier is 3 years parts and labor.
Driver: The warranty on the
driver is 5 years parts and labor.
