Overview

Our take on the Polk Audio DSW PRO 550wi

Feel the rumble in your movies with this powerful subwoofer

Pump up the excitement on movie night with the Polk DSW PRO 550wi. It sports a 10" woofer driven by a muscular 200-watt amplifier that'll make your hair stand up during intense action sequences. This advanced subwoofer features Polk's exclusive Feed Forward™ technology, which reduces audible distortion without limiting volume. You get quick, precise response throughout the sub's entire frequency range, even at wall-shaking volume levels.


Sounds great no matter where you place it

The PRO 550wi also includes the Polk Room Optimizer™, an ingenious feature that lets you specify the location of your sub with one of four options — corner, mid-wall, in-cabinet, or mid-room. The Optimizer then automatically equalizes the sub's response to ensure smooth, clean bass from that position. You can easily access this function, as well as the volume control and phase switch, with the included remote, so you can fine-tune the bass from your favorite listening spot. Removable feet let you position the PRO 550wi for either front-firing or down-firing operation, whichever you prefer.

Killer sound....

Features

Driver: The DSW PRO 550wi uses a 10" Dynamic Balance composite polypropylene cone driver for deep, accurate response with low distortion. For a smoother response and improved durability, the woofer utilizes a rubber surround.

Klippel Optimized Woofer: By using a state-of-the-art Klippel Distortion Analyzer, Polk Audio is able to optimize the woofer's motor structure, voice coil alignment and suspension for the best possible performance even at extreme listening levels.

Class D Amplifier: The subwoofer is powered by a high-current Class D amplifier producing 200 watts RMS power (400 watts Dynamic power) that supplies clean power for loud bass and a wide dynamic range necessary to recreate a life-like experience in your home. The efficiency of a Class D digital amplifier translates into high-power, and cool, reliable operation with low distortion.

Feed Forward Distortion Suppression Technology: This technology maximizes acoustic output as it reduces audible distortion. Feed Forward is a zero latency system that maximizes dynamic output of the subwoofer system without relying on slow responding feedback techniques. What you'll hear is quick, precise bass output with minimal audible distortion, even at loud volume levels.

Enclosure: The DSW PRO 550wi features a bass-reflex enclosure with non-resonant MDF construction and internal bracing for deep bass impact with superior detail and accuracy. The subwoofer's enclosure's durable onyx black finish can be painted to match your room decor, if desired.

Downward Radiating Slot Port: The DSW PRO 550wi features a downward radiating slot port which lessens turbulence, noise and distortion. The result is deep, clean and accurate bass.

Video Shielded: The DSW PRO 550wi is magnetically shielded for placement near video monitors. You should still allow at least 18" of space between your subwoofer and any tube television. LCD, DLP and Plasma TVs are not affected by magnetism.

Frequency Response: The overall frequency response for the subwoofer is 23-160Hz, and the -3 dB frequency response is 30-125Hz.

Repositionable Feet: The DSW PRO 550wi features repositionable rubber or spike feet which allow you to orient the subwoofer on its "back" to turn it into a front-firing woofer when you want to hide the subwoofer away in cabinets. There is an optional woofer grille (item # 107DSW500G, sold separately) available when the subwoofer is used in a front firing application.

Note: The remote control may not operate when the subwoofer is placed in a cabinet with the driver facing into the room. If this occurs, adding an IR repeater will enable the remote control to communicate with the subwoofer.

Controls

IR Wireless Remote Control: The DSW PRO 550wi comes supplied with a credit card sized IR wireless remote control which operates the following subwoofer's controls - Volume, Mute, Phase, Night and Polk Room Optimizer. All commands are sent to the subwoofer via IR control. The IR receiver is located on the front of the subwoofer when the subwoofer is its downward firing configuration. There is a blue LED behind the woofer's logo badge which blinks to confirm the subwoofer has received and responded to the remote's instructions. The LED feature can be turned off.

Note: The subwoofers crossover setting must be set using the controls located on the rear panel of the woofer.

Polk Room Optimizer: The DSW PRO 550wi's remote control incorporates the Polk Room Optimizer (PRO) feature. The Polk Room Optimizer feature allows you to place the subwoofer where you want it in your listening room. Based upon the four most common room placements for subwoofers, the Polk Room Optimizer maximizes sound quality for you, smoothing out the bass response that a particular room placement creates. There are four push-button room equalization presets on the remote that correct for room boundary effects for typical room placements: "cabinet," "corner," "mid-wall," and "mid-room." The result is great bass performance no matter where you place your DSW PRO 550wi subwoofer.

Night Mode: Night Mode compresses the dynamic range of the woofer's output, so you hear low-level bass detail at lower volumes.

Volume Control: The DSW PRO 550wi has a push button volume control to adjust the volume of the subwoofer relative to the other speakers in the system. The volume is adjustable from 0 to 40. The blue LED on the front panel will indicate the volume level using a combination of short and long blinks. The volume can also be adjusted using the supplied wireless remote.

Phase Switch: The subwoofer's IR wireless remote features a phase control which allows you to select 0-degrees (normal), 90-degrees, 180-degrees (reverse) or 270-degrees. This control enables the subwoofer to blend more seamlessly with your main speakers. If the bass sounds muddy or unclear, using the phase control can sometimes strengthen the bass "attack."

Low-Pass Filter: The DSW PRO 550wi offers a continuously variable low-pass filter, adjustable from 60-120 Hz. The cut-off frequency must be manually set from the subwoofer's control panel.

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 15 minutes after the signal stops; "On", which keeps the unit on and "Standby", which turns the unit off. The LED power indicator glows green when the unit is on, red when the unit is off and yellow during standby mode.

Connections

LFE (Unfiltered) Input: The DSW PRO 550wi 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/Outputs: The subwoofer has gold plated left and right RCA Line Level inputs. The 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. The line outputs allow you to send a filtered signal to a power amplifier to drive bookshelf speakers.

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 sends it to the subwoofer. The speaker level outputs send a filtered signal to your connected speakers.

2 questions already asked

Purchased a new DSW PRO 550wi on October 10, 2015 to replace the 500. It is still working. They made some small changes to the control panel. [ James  Jun 08, 2017 ]
I had a similar situation with a Polk DSW PRO 500, so I ordered a Polk DSW PRO 550 from Crutchfied as a replacement. Meanwhile I repaired the 500. Same symptoms as yours. Mine had a small capacitor that failed in the power supply circuit. (shorted) The capacitor cost less than $1. I had a Infinity prior to the Polk that got to where it refused to wake up at low volume levels. [ James  Jun 08, 2017 ]
NO JON IT IS NOT WIRELESS. MANFRED W [ MANFRED W  Aug 05, 2014 ]
Yes . But you have to buy the wireleess adapter separate . This is aatached to the back. Works well in my unit. [ RODRIGO C  Jul 21, 2014 ]
It is, but you will need to purchase the Polk wireless kit separately, which includes the transmitter and receiver. Unfortunately the kit is not included in the subwoofer price. [ JASON M  Jul 20, 2014 ]
No. It can be wireless but you need to buy extra adapter and connect to sub. [ DARIUSZ  Jul 12, 2014 ]
it's a hardwire connection [ MARTIN  Jul 10, 2014 ]
It can be with the connection on the back but still very good sub [ JEFFERY L  Jul 10, 2014 ]
I have mine wired, but it is wireless ready. You may have to buy some separate components (depending on your receiver?), but it is wireless capable according to the manual. Page 7 of the manual should tell you everything you need to know about setting up the sub wirelessly. I tried to add a link to the manual but it was not accepted in this text box. Go to the Polk audio website. Click "Support" at the top of the screen and enter "550" in the text box and the manual will be the first one on the list. I hope this helps! [ RICHARD  Jul 10, 2014 ]
No. It's hard wired to the receiver. [ BRIAN  Jul 10, 2014 ]
No; but it has a wireless remote control. [ JEFFERY A  Jul 10, 2014 ]
Indeed it is, just keep in mind the fact that you still have to plug it in to an electrical outlet, but the length of cord it comes with is quite generous. [ DANIEL  Jul 10, 2014 ]
