Polk Audio PSW108

Overview

Our take on the Polk Audio PSW108

Add serious low-frequency impact to your movies and music with Polk's PSW108. This powered subwoofer delivers solid, accurate bass thanks to its 50-watt RMS amp and 10" woofer. The cabinet is constructed from non-resonant MDF, and is reinforced with internal bracing for superior bass clarity. The PSW108 is a great way to round out a home theater system or add depth to your stereo music without breaking the bank.

Flexible inputs and controls

Polk makes it easy to integrate the PSW108 with your existing system. You can hook your receiver up to the sub either through the line-level or the speaker-level connections. The continuously variable low-pass crossover lets you dial in the sound to match the PSW108 to the rest of your speakers. And a phase switch lets you tweak the sub's output for more precise bass response.

Great sub-woofer!

Written by: John H from Dublin, OH on July 12, 2016

Crutchfield Customer Review (What's this?)

I purchased this sub-woofer based on the feedback and reviews I found. I am happy to report that I found almost exclusively positive comments, and further that they were are based in reality! I love the sub-woofer and how easy it was to set up and use. It is a little larger than I expected, but I have only owned one sub-woofer previously, and it was part of a home-theater-in-a-box set. I love the easy access to the volume knob in back, and the kids love it as much as I do!

Pros: Sounds great, easy to set up and use. Volume control in back; with stand-by on/off switch.

Cons: None.

Crutchfield Customer Review (What's this?)

I bought this sub to compliment my speakers in my dorm. I love it so far, it really adds a lot to movies and music that I had been missing. It seems well built, but it isn't as heavy or large as I expected it to be. So far it has been well worth the money, in my opinion.

Pros: Multiple types of input/ output. Adjustable volume knob. Relatively small size. Fantastic sound.

Cons: none, so far.

Subwoofer makes a big difference for My Yamaha SRT-1000 sound bar

Written by: Johnofsylvan from Englewood FL on March 21, 2016

Crutchfield Customer Review (What's this?)

This subwoofer has an energy saving position. It is the middle position on the power switch. When a music signal is sent to the subwoofer the amp turns on (indicator light goes from red to green). When the music signal stops the amp returns to standby. My Yamaha SRT-1000. Adequate bass to fill our large great room

Pros: The speaker box has multiple connection options.

Cons: The speaker box is too big to hide. I was use to a Bose I could tuck between furniture.

Nice Sub

Written by: Dave Z from cheyenne, WY on February 29, 2016

Crutchfield Customer Review (What's this?)

Arrived in perfect condition. Bigger than I thought. Great look sounds great. Great addition to my stereo. I'm not using it for home theater and it works well. My only gripe is 2 of the speaker cover pegs broke off removing the cover. I pulled them out an super glued them. I was very gentle removing the cover. Looking it over I noticed some of the pegs are tweaked and don't line up quite right putting stress on the plastic pegs so they broke.

Pros: Good sub, good price.

Cons: Cheap plastic pegs holding on the speaker cover.

Thank you for your help/information about sub-woofers.

More expensive Polk subwoofer blew amp 1 month after 3 year warranty so went with cheaper less powerful PSW108 . Excellent sound with easy setup and great sale price. Very attractive

Pros: Cheap great sound easy setup very attractive volume control auto turn off

Great sub for the price

Written by: JoeM from Michigan on January 10, 2016

Crutchfield Customer Review (What's this?)

My previous 12" Infinity sub of 15 years finally kicked the bucket, so I was looking for an economical replacement. This sub is great for the price. Not quite as much rumble as my previous sub, but it fills out my system nicely. It also sits in a large room, which was a small concern with a 10" sub. I am totally satisfied.

Pros: Great price and has enough power.

Cons: None

Written by: Brennan W from N Charleston SC on January 3, 2016

Crutchfield Customer Review (What's this?)

Sounds great, I use mine in a full service home stereo setup. I have 4 floor standing speakers and this powerful sub. I mostly use my system to listen to music but also watch movies from time to time. I am very pleased with this sub, gives me the bass I was missing. I may add another one day to round out my system even more. Unit looks great too, high quality craftsmanship.

Pros: Sound, good punchy bass Looks great, high quality

Cons: None, this unit is a top notch value priced powered sub. This unit will produce what I would consider to be unacceptable levels of port noise at high volumes with music with boomy bass. But at the price point of this unit and the fact that I don't listen to a lot of boomy bass music this unit is a solid 5 star powered sub

Written by: Bradley from Texas on October 26, 2015

Crutchfield Customer Review (What's this?)

I added this unit to my 'polk' home theater set up. Driven by the Onkyo TX-NR737. Deeps are clear and solid. Provides good rumble to accompanying mids from center speaker. Size surprised me (to the positive), feels 'bigger' than advertised. Solid and well built. Could be an end table in a crunch, but probably not the best place to put your drink :-)

Pros: Fit and feel, "rumble", price, sound.

Cons: None so far

Small but forceful

Written by: Mark from Georgia on September 26, 2015

Crutchfield Customer Review (What's this?)

Over the last year I've been building up a small system in my home office. I hadn't spun a record in a decade and a Saturday spent wandering used record stores with a friends inspired me to dig out an old turntable and watch the wobble of old vinyl myself. I tried to resurrect some old gear but it had reached it's time, so started a small purchasing adventure, all through Crutchfield. A new NAD CD player, new Cambridge Audio amp and some small Polk bookshelf speakers had me happy for a year. But there was something missing, that little thump of sound that makes you feel as much as hear. I bit the proverbial bullet and ordered this basic subwoofer. My first unit was defective, but the customer service here at Crutchfield had a new one on its way within hours of my call - I've been buying stuff from them for nearly 30 years and they have never failed me. On to the subwoofer itself ... it's small, relatively inexpensive and I was just looking for a little life at the low-end. I don't crank the volume up as I'm in a small space and this fits the bill perfectly. It could probably rattle a few windows, but the way I'm using it is just to give a little bit of bass response. What I love most is the tightness of the sound - it's there, it's present, it's forceful, but it isn't all booming and thumping. It's a purposeful sound that, I think, brings the musicality out as the performers and engineers intended it. Exceedingly happy with the purchase.

Pros: Tight, forceful sound that isn't overwhelming or boomy.

Cons: First one (an open box) was defective, but the customer service from Crutchfield was excellent, getting me a new one right away.

Polk PSW 108 Subwoofer

Written by: BW from West Virginia on July 19, 2015

Crutchfield Customer Review (What's this?)

Polk makes great products. I was a bit concerned when I purchased this product only because I have an older "system" and I was't sure if it would work. It worked with my system as soon as it go plugged in with simple instructions. Even better the product was shipped and I had it in 3 days. Wow was I surprised. I have purchased from Crutchfield before and they never fail to give the best service for their customers. Thank you Crutchfield.

Pros: Excellent Polk product with excellent sound. Easy to connect and up and running in no time.

Cons: None.

Proven Quality and Performance

Written by: Pat from Arizona on June 17, 2015

I have a PSW10 that is over 10 years old. It is used in an all Polk surround system with TSi100 front, center, and rear speakers powered by an Onkyo receiver. This subwoofer has performed very well for the entire time, and is more than powerful enough for a 16 by 16 foot living room. We have never had it a maximum volume, and will vibrate furniture during loud LFE sections of movies with clear and unmuffled bass. This sub is a huge value, and if mine failed I would buy another.

Pros: Quality Performance

Cons: None

Delivery of Bass is what i wanted and is what I've received with these Subwoofers.... A little secret.. I exchanged both of my Bose subs for these Pork Audio subs. If you don't tell i want tell. Have a great Evening. Thanks again to Crutchfield..

Perfect for the DIY'er - 5.2 Ch System

Written by: JimBo from Nevada on November 22, 2014

Crutchfield Customer Review (What's this?)

Great product for the money. I have this hooked up to an Onkyo 5.2 ch surround in my living room which is all tile floors (ceiling speakers @ 10 ft). Sound is perfect with little to no reverb. I combined this sub with PolkRC 80i (2 Fronts), RC60i (2 Rear) and an MC80 (Center). Great "bang for the buck". Recommend this to anyone who is looking for a level right below theatre HD quality.

Pros:

Cons:

Good subwoofer for small systems and rooms

Written by: djEric from California on November 10, 2014

Crutchfield Customer Review (What's this?)

This subwoofer works well with my small AudioEngine speakers and desktop computer -- really gives some bottom end that desktop speakers just can't provide. I chose a smaller system for my desktop because if you are working you just don't need to be knocked over with sound. With this combo, you can keep volume levels low and still get good fidelity.

Pros: Plugs right in, good fit, great sound for its size. Not a gamer, but sound holds up fine if you want to crank it up for movies or music videos.

Cons: might be a little meek in thunder dept, you will need something bigger for a larger room.

Written by: RustyF from Atlanta, GA on August 29, 2014

Crutchfield Customer Review (What's this?)

This replaced a worn out infinity 50 watt sub in a bedroom. Simple installation & setup in 5.1 system was simple.

Pros: Lots of rumble out of a small unit. This sub would work well in a larger room too. The sub this replaced was down firing and I like to front facing speaker much more. So far I am very pleased with this sub.

Cons: The speaker is lite, not sure if this will last as long as the infinity that was 13 years old. The unit was delivered in a very damaged box and had some cosmetic damage. This was done by UPS shipping and Crutchfield worked with me and provide 2 acceptable solutions.

Wonderful Sub

Written by: Mike from Rockford, IL. on March 26, 2014

Crutchfield Customer Review (What's this?)

I was able to purchase this product from Crutchfield for an unbelievable price and it arrived in just a day. I was pleased to be able to refer to Crutchfield's information on the use of sub's within a Home Theater system as this assisted in my purchase. This sub is excellent. Very tight bass and sounds great with movies as well as classic rock when I want to relax to some music. I have a pair of vintage floor standing Advent front speakers and this Polk sub takes on those low frequencies allowing my Advents to sound brand new. I love this sub and you can't beat Polk for warranty with a five year warranty on a speaker. I am purchasing an additional one as well.

Pros: Extremely affordable, tight, accurate bass, easy set up

Cons: I could sure use a line out on the back of the sub in order to "chain" a second sub to this one.

Polk PSW108 Subwoofer Does the Trick

Written by: Hal H. from Columbus, OH on February 24, 2014

Crutchfield Customer Review (What's this?)

After purchasing a pair of Polk TSi 300 floor standing speakers (which have a decent sound on their own) a year ago, I wanted something that would round out my surround sound system and add just that extra base in a small living room. The PSW108 added just enough to enhance both the surround sound as well as standard stereo music, without a major $ investment on my part. It makes the system sound great in a small space and does not overwhelm the base. If I ever move the system to the larger room, I'll try the PSW108 first but may need to upgrade to a higher wattage sub. However for the space I have right now, it's perfect. As always, Crutchfield's customer service was exceptional helping me navigate the purchase using 4 different gift cards. I liked the free shipping and having the sub delivered to my doorstep in just 2 1/2 business days.

Pros: More than enough power for a small space.

Cons: I wish the Polk user manual was a little more detailed.

Written by: 31Voldog from Cleveland, TN on January 11, 2014

Well worth the money. Vocals and all high end sounds are clear and crisp. Using controls on Onkyo NR509 allows various adjustments to fine-tune to anyone's preference. Must have for home theater, but enhances music as well.

Pros: Great sound, great price, ease of setup/install.

Cons: Be prepared to raise you TV, or purchase new console; it is big.

Great Budget Subwoofer

Written by: PureDark from Taber, AB on January 6, 2014

For what it is and for the price this sub is amazing. I have it paired with two Polk Audio M20's ($130CAN on sale) and they are a wonderful match. I am running them off a Cambridge Audio C500/P500 so the source is solid. I wired it through the high level inputs and set the crossover to 80hz. It meets the M20's wonderfully in my small room. You may read complaints about not enough punch or distortion but for under $100 the sub does very well. During movies I can feel the thunder and for jazz, classical, and rock it it very smooth.

Pros: Great price (only buy if it's on sale) Great sound for it's price Input options (high level and two channel line level) Auto-on/off

Cons: None so far

Totally awesome product!!

Crutchfield Customer Review (What's this?)

If you have a nice system , and do not have a subwoofer , you are missing out. The Polk Audio is the best thing I could have done for my system , the sound is truly incredible, I have some JBL bookshelf speakers and this thing fits in with them perfectly. You can adjust the settings easily and I do not suggest this for anyone living in an apartment with close neighbors. The house will shake when this thing is kicking, for real...

Pros: sound , a real deal for the money

Cons: NONE

More Than I Expected

Crutchfield Customer Review (What's this?)

I have replaced an Optimus (Radio Shack) sub. No controls. Attach the wires and what you get is what you get. The PSW108 is awesome! I am using Polk bookshelf speakers. Since the PSW108 is powered, it's not a problem adjusting the sub to match the speakers. The PSW108 could easily accommodate much larger speakers. The sub "sleeps" after you shut down the audio and comes right back on when it senses audio. It's a feature I like. I've always thought audio equipment is a bargain. Twenty years ago, you wouldn't be able to find a sub of this quality for $180. Describing how music sounds is difficult. Let's just say there is butt kicking bass that is not out of place. Rock 'n' roll is wonderful and some jazz albums have extraordinary low passages. Movie soundtracks are the killer. When a door slams, you feel like you're in the room. When that music comes on, Sally Jo is going to be sorry she walked in the room. You can feel it. There are times I like to make the walls shake, but when the music is turned down low, the PSW108 is still working. At low listening levels, you still get everything. I'm impressed.

Pros: powerful, adjustable, good looking, easy, solid

Cons: duuuuh...can't think of any

Crutchfield Customer Review (What's this?)

I connected this to a Denon 1913 AV Receiver and Amp, Center Speaker and 4 ceiling mounted speakers. The Audyssey automatic tuning did a great job of identifying one speaker connected backwards and then equalizing speaker and room. The subwoofer really can tick the wife off . . . not intended but what can I say.

Pros: Great price, good performance

Cons: None

Crutchfield Customer Review (What's this?)

Wow! This little sub cranks out some low frequency. I recently purchased this sub, paired with an Onkyo TX-8255 receiver and a set of Polk TL1 Blackstone bookshelf speakers. I'm seriously impressed with the sound. I'm on a budget, so for the price I certianly got my money's worth. Glad I don't live in an apartment.

Pros: clean lows, loud, no distortion.

Cons: It's pretty big. if you have a small space you'll be struggling to find room.

Good bas, seems solidly built

Written by: Bobafet512 from IL on September 19, 2012

Crutchfield Customer Review (What's this?)

Looks nice, puts out good bas. I don't know much about two inputs like this one has, but my advisor said I could hook the single sub out cable from my receiver to either one of the inputs on the sub and it should work. It did. Perhaps Crutchfield could put that information somewhere in the description or their review (unless I missed it).

Pros: Looks good, puts out good bas, Gotta love Crutchfield's free shipping!

Cons: A little on the pricy side for me.

Great Product

Written by: CurtT from Layton, UT on July 25, 2012

Crutchfield Customer Review (What's this?)

This is a fantastic subwoofer for the money. It doesn't distort even at high volume. I turn it down so it doesn't overpower the rest of my system. Sounds better than my old one for about the same money I paid 10+ years ago. I gave it 4 stars because I'm sure if you spent quite a bit more money you could get one that would qualify for a 5 star rating.

Pros: Easy set-up.

Cons: None so far!

Features

10" Driver: The Polk Audio PSW108 uses a front-firing 10" composite polymer cone driver (with foam surround) for deep, accurate response with low distortion.

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

Motor Structure: The PSW108 utilizes a powerful motor structure for a higher BL responses (the measure of the motive force applied to the cone) that results in louder, deeper and punchier bass.

Compression Circuitry: The woofer's Compression Circuitry limits distortion at high volume levels.

Amplifier: The subwoofer is powered by a high-current amplifier producing 50 watts RMS/100 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.

Enclosure: The PSW108 features a bass-reflex enclosure with non-resonant MDF construction and internal bracing for deep bass impact with superior detail and accuracy. The Polk Audio PSW108 is available in a black wood-grain vinyl-wrapped finish.

Front-Firing Port: The powered subwoofer's front firing port allows the woofer to be extremely efficient and provides more bass impact for your home theater experience.

Not Video Shielded: The subwoofer is not magnetically shielded, so it is not recommended to place it next to tube TVs and video monitors. Though LCD, DLP and Plasma televisions are not affected by magnetism you should allow at least 18" of space between the subwoofer and any TV.

Placement: You may place the subwoofer anywhere in your room, but it will perform best when it's on the same side of the room as your system's front speakers. Also, placing the subwoofer near a wall or in a corner will increase its loudness.

Controls

Power Switch: The subwoofer has a 2-way power switch on the rear panel. When On/Auto is selected, the subwoofer turns on automatically when an input signal is received and off 15 minutes after the signal stops. The LED power indicator glows green when the unit is on and red when the unit is off.

Volume Control: The PSW108 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 0-degrees (normal) or 180-degrees (reverse). If the bass sounds muddy or unclear, toggling the phase control can sometimes strengthen the bass attack.

Low-Pass Filter: The PSW108 offers a continuously variable low-pass filter, adjustable from 80-160 Hz.

Connections

Line Inputs: The PSW108 has gold plated left and right RCA line level inputs. If your receiver or processor has a single subwoofer line output, you can connect it to either the left or right line input jack. For receivers having subwoofer or stereo preamp outputs that do not contain their own low-pass crossover, the PSW108 will handle the low-pass filtering. If the receiver's subwoofer output or "LFE" output has a built-in low-pass filter, the PSW108's low-pass control should be turned fully clockwise (160Hz).

Note: The PSW108 does not have a dedicated LFE input.

Speaker Level Input/Output: The subwoofer has spring clips for the speaker level inputs and outputs. The subwoofer's low-pass filter sends bass frequencies (based on the setting of the filter) to the subwoofer. The speaker level inputs and outputs are shorted together, so the output is not crossed over. You should set you receiver's front speaker setting to Large.

7 questions already asked

I you have a subwoofer input on the surround system, yes [ ANTHONY  Mar 11, 2016 ]
I forwarded your question to an Advisor and they responded with the following: Yes, the speaker level outputs are designed to pass through the signal and power from the speaker level inputs on the Polk PSW-108. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Oct 05, 2015 ]  Staff
Absolutely. You would simply run a subwoofer (RCA style) cable from the Subwoofer Pre-out on the back of the Denon receiver to the Line In on this subwoofer. [ Jeff  Mar 18, 2015 ]  Staff
Thanks for your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine if this will work and help you make the best choice for your system and your budget. [ Krissy  May 06, 2014 ]  Staff
Yes, it should be fine, use a quality RCA cable. I have this with the Polk RM7 set and it makes all the difference in the sound. [ BRADY L  Dec 25, 2013 ]
Yes, this sub will work with A/V receivers with a single sub out jack. You connect the sub out from your receiver to one of the sub's input jacks and leave the other open. My Yamaha is connect like that. [ JAMES F  Dec 22, 2013 ]
Yes, you can wire the sub with just one phone plug. I believe that a subwoofer is mono anyway. You can also run speaker wire from the right/left speaker to the sub as well. [ LESLIE NEIL  Dec 21, 2013 ]
I have a single our on my Denon AV 1913 and it works great. Good luck. Don [ DONALD J  Dec 21, 2013 ]
