Polk Monitor XT12 Powered Sub - 12" Balanced Woofer & 100W Class A/B Amplifier, Low-Resonance MDF Cabinet & Removable Grille, Dolby Atmos & DTS:X Compatible, Home Theater Subwoofers, Midnight Black

I was replacing an old, much more expensive Velodyne sub (may it RIP). Not wishing to spend a fortune on one this time around, I opted for this Polk sub. I had some concerns about the quality attainable in this price range, but I knew Polk as a quality brand, and I was pleased with the purchase. Yes, this sub can shake your house if that’s what you want. It can probably shake your neighbor’s house, too, if you turn it up some more. But I was after neither of those things. It was clean and accurate base which adds color to the sound without being overwhelming I was looking for. In fact, from where I stand, if you are playing an audio track, and one can tell right away that there is a sub, it’s probably too loud. Clean and accurate base is exactly what this sub delivered for me. Someone here mentioned that auto-on wasn’t working well. It does work very well for me. Just don’t limit LFE output too much on your AMP. I have it limited to 120 Hz on the receiver to make sure a good amount of output flows into the sub to reliably trigger auto-on. Then I limit the frequency with the sub’s own crossover some more to achieve a perfect balance. If I were to make a wish, it would be to have an LED indicator on the front of the sub to see that it did turn on, like my old sub had. Assuming nothing fails through it is certainly not a necessity and would require an add-on to materials and cost.

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 Towers 2 XT30 Centers (yes, two centers, and clarity is unreal) 2 OWM3s for rear surround 1 XT12 Subwoofer Powered by a Denon AVR-S570BT I 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.

Legit amazing! 10/10 Price was perfect, would 100% buy again! 🥰 But warning for people who live in apartments, if you’re not careful someone is definitely going to complain. Unless your goal is to get people upset, then ignore this warning because this will work for that 😂 Also if you roll up like a foam soundproofing wall panel, and put it in the rear port (but not like fully blocking off the port though), it will make it a bit punchier. Not that it needs that to be done in anyway, but if you’re having this in a small room then doing that helps in ways that I can’t explain with words. It easily connected to my PC via optical output, which goes to an optical splitter. Then the optical branches off to my soundbar optical input and my GoXLR optical input. Then from the GoXLR I use the 3.5mm line out, converting to over to RCA into the subwoofer. This allows me to get perfect, easy and independent remote volume control of the subwoofer via the GoXLR sliders, while still having a master control on the PC that will adjust both the soundbar and subwoofer at the same time, resulting in perfectly fine tuned sound quality with absolutely no distortion.

Sub sounds great!!! Easy to setup and works great with my Onkyo Reciever! Goes great with my other Monitor speakers.

I had a JBL 5.1 and it sounds so bad. Bought Polk xt60 + xt12 and I am very happy already. Boom boom boom. Very powerful

Clean smooth bass or thunderously loud bass depending on your preferences and your choice of sub output settings, combined with multiple receiver connection options (including working with most old school receivers) and has built-in rear adjustment control options with a LED indicator, all make this an unbeatable deal considering competitors much higher prices for a comparable sub. The solidly built cabinet and removable grill have an appearance that should blend well into any surroundings. Weighing in about 40 pounds this subwoofer is substantially heavy. Could not be more satisfied with this purchase. It definitely brings bookshelf speakers to life!

Excellent Dolby atmos subwoofer

Complete junk. Never turned on. Fuse is good. Could not ever get it to turn on

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!

Som de qualidade. Caixa muito bem acabada.

Un sub con una enorme potencia . Es lo que faltaba para el sonido en casa , desde que lo conecté todo cambió! Una gran compra

This thing is a freaking cannon !! Legit completes my 5.1 setup, this sub is equivalent to a concert at home given the right setup. VERY IMPRESSED !!

Es el complemento perfecto de mi equipo, suena excelente y enriquece el sónido de la música y las películas. No te arrepentirás y mejor aun si la compras en oferta.
