About the Polk Audio PSW505

Who's afraid of the big, bad Polk PSW505? Probably anyone who's not ready for loud, low bass, delivered with maximum precision and impact.

Who's afraid of the big, bad Polk PSW505? Probably anyone who's not ready for loud, low bass, delivered with maximum precision and impact.

Polk's PSW505 boasts a very sturdily built, slot-loaded enclosure — by reducing port turbulence and distortion, the Slot Load Vent sends out bass that fills your room and still retains detail and shape. Inside this enclosure, Polk's hidden a brawny 300-watt RMS amplifier, which powers the high-quality 12" long-throw woofer. The woofer's Hi-Roll foam surround gives the cone more flexibility for back-and-forth movement. This beast sends out a lot of sound!

The PSW505 doesn't stop there, either. Along with accurate lows for rounding out your music, and all the deep bass growl you crave for home theater, this sub offers flexible connection options and good looks. An unfiltered LFE input lets you maintain precise bass with your Dolby Digital home theater. Speaker-level inputs and outputs and a line-level input add to your options. And the cool styling, with silver details and a real wood veneer, is another popular touch.

Features

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 foam surround.

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 power.

Enclosure: The PSW505's solid MDF enclosure (including a one inch thick front baffle) suppresses enclosure panel resonance for distortion-free, accurate response.

Slot-Loaded 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 bass response.

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.

Volume 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 "attack."

Low-Pass Filter: The PSW505 offers a continuously variable low-pass filter, adjustable from 60-120Hz 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 frequencies.

Inputs and Outputs Notes

LFE (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.

Note: If the receiver's subwoofer output is unfiltered, you should use either the left or right Line Input of the subwoofer.

Line (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.

Speaker 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.

Specifications

Frequency Response: The overall frequency response for the subwoofer is 23-160Hz, and the -3 dB frequency response is 28-125Hz.

Warranty Notes

Amplifier: The warranty on the amplifier is 3 years parts and labor.

Driver: The warranty on the driver is 5 years parts and labor.
