Looks good and great features/sound for the price
This sub is great for the price. Get it on black friday and save some money. Most of the equivalent subs of this size are 300+ bucks. A little misleading though, measuring from the edge of the rubber from one side to the other side of the speaker is about 8 inches not including the 1/4 in area for the screw holes. So to me this is more of a 8” sub and overall is the size of yamahas 8” sub. Not complaining though, i do like the more compact size as subs used to have huge heavy boxes in the past. This one says 23lbs so not bad overall. Its your typical black vinyl veneer look and comes with power cord and instructions. Basic controls are power switch, phase switch, volume, low pass filter and the lfe or stereo rca jack inputs. Most people will like the phase switch at 0 as it matches their other speakers phase, but i say try both ways and see what you like. Thats it and its simple and perfect for entry level sound systems. You will need a sub cable which is a single rca male to rca male. Im using it for my computer and have a douk ampapa 300w amp with upgraded muses 02 opamps and sony cs5s that i purchased a few black fridays ago at a great price. The ampapa amp has a mini 3.5 jack output and using the polk lfe rca input. The polk has an adjustable low band filter so will cross this sub over at about 80hz as to me thats the cleanest sounding xover point. Anyways, overall if you want a lower cost decent sound for your stereo or even computer or tv, this setup is great for a small to medium size room.Review for height monitor x190, got these on black friday as well. I have 6 wharfedale diamond bookshelfs and center with a sub for my main tv hooked up to my onkyo rz50. It has outs for atmos height so after reading reviews got this on black friday sales. Overall a very simple maybe 3 inch full range driver in an angled mdf box. It has a nice grayish color grill and speaker posts that accept wire or banana plugs so simple install. I need to se up my dirac live settings then will update review. Other then that. Speaker looks fine in quality but super simple design so get them on sale.

Incredible Value, Very Impressed!
One word, value. I have an SVS-1000 and I get similar bass quality from this Polk XT10. I’ve been very impressed with this sub. Fits perfectly under the desk, works perfect with my NXZT pc speakers. Excellent power, ease of setup, sound quality, range, durability, and looks modern and professional. Love Polk. My main living setup has been Polk for years now. You go Polk!

Simply a game changer stream XM from my iPhone
Decided to get out my old school 1970’s receive, add a Bluetooth interface and some quality sounding speakers to take me back to my Wonder Years. Now I’m streaming Sirius XM from my iPhone 17 to an Auris bluMe Pro via BT-5.3 in AAC 24bit @ 44. 1KHz (can do 32bit with the proper Andriod phone) into my vintage 1970’s SONY STR-VX3 receiver, going out to these Polk Monitor XT20’s (and my existing Advent Calypso patio speakers with the A/B switch). What can I say? SImply AWESOME! Definitely big value for your buck.

Polk Audio Home Theater System Review Blown Away!
Let me start by saying I never leave reviews. But after finishing my dedicated theater room and firing up my Polk Audio setup, I had to make an exception. Simply put: I’m blown away.My system includes:2 Polk XT70 Towers2 XT30 Centers (yes, two centers, and clarity is unreal)2 OWM3s for rear surround1 XT12 SubwooferPowered by a Denon AVR-S570BTI spent around $1,200–$1,300 on this setup, and it performs like something three to four times that price.I tested it with everything from Star Wars, Top Gun: Maverick, Mission: Impossible, Transformers, and the full Marvel catalog. Every explosion, orchestral swell, and whispered line is crisp, dynamic, and immersive. The sub hits hard when needed, and the highs and mids are perfectly balanced. Dialogue clarity is exceptional, and music playback is just as impressive, with a wide soundstage, tight bass, and clean highs.As someone working in film and television, I use this system to review projects before sending them to streaming platforms. It gives me confidence that our audio is tight across all frequencies and plays beautifully on real-world systems.If you’re looking for a budget-friendly, high-performance setup, get yourself a Polk system and pair it with a Denon AVR. Trust me, you won’t be disappointed. The smile on my face during the first listen said it all.

Good sound, maybe bad QA
The sounds is beautiful – man I have really been missing out the past few years – and setup was a breeze. Auto on works just like you think it would, a bonus is that it stays on for a bit even after the signal drops out so it doesn’t miss anything. While it isn’t timbre matched to the other speakers, they are all Polks and seem to drop seamlessly into my setup (Signature Elite S20/30).However.Take it out of the box I can hear and feel it delaminating on one corner. Time will tell if that gets worse or I just forget about it (hopeful for the latter). Thankfully it’s on the side where it’s almost touching my TV stand and after the initial inspection, my cat has deemed it unimportant. As it doesn’t really affect anything, only taking off 1 star. (The cat is specifically why I have this sub: down firing and no fabric on the front.)Oh, and in case this saves someone a minute of frustration: make sure your amp has the sub turned ON if you didn’t have one connected before (and your amp requires speaker setup). I didn’t initially and was very confused why it wan’t plug and play!

A good pair with Punchy raspy clear vocals paired with a Yamaha amp. Adding a subwoofer completed the setup and it’s time to enjoy!

Abbinate ad un amplificatore Yamaha AS 201, giradischi Audiotechina AT LP120X e collegamento con dispositivi bluetooth, ne sono subito rimasto soddisfatto della qualità del suono, diffuso in un piccolo studio di 12 mq. Suono ben enfatizzato a tutti i livelli. Certo ascolto esclusivamente musica rock, quindi magari con generi diversi potrebbero rilevare difficoltà che io nn trovo. Ho acquistato nel frattempo anche un’altra coppia di altro noto produttore, con woofer e cabinet più grandi, (collegati all’altra uscita dell’ampli) al doppio di prezzo…. bè a parte che i bassi sono meno presenti e persistenti, la qualità e pulizia del suono, la precisione e la resa volumetrica è superiore!Il mio è un giudizio nn da esperto, ma il confronto istantaneo fa emergere le differenze subito e con buona chiarezza!Ottime x me!

A great Subwoofer, regardless of cost!This is a very good subwoofer, solidly build at a very reasonable price, ESPECIALLY IF YOU CAN GET ON SALE. It has all the inputs you need, including speaker level inputs. Arguably this is the best way to hook up your sub, because it gets the same input as the main speakers and then low pass filters it. I have tried this sub with a 35 W rms/ch amplifier and relatively small hi-fi speakers and a 100 W rms/ch amplifier with large floor standing hi-fi speakers. In both cases it really boosts the low frequencies making the sound full, deep and well separated. For starters, set the volume level to just under half and the low pass filter to 80 Hz, listen to a variety of music genres and adjust to your liking. The sound output is deep, musically pleasing and you can feel the low bass notes in your gut!
