I bought the Polk Monitor XT12 subwoofer, to complete my MXT series of speakers. I have a pair of MXT70 tower speakers up front, an MXT30 center channel, a pair of MXT60 tower speakers that I use for side surrounds, and a set of MXT20 bookshelf speakers at the rear.Now all of my speakers match, and are from the same series, and my home theater sounds amazing.The MXT12 added the punch I needed, over the 10 inch Sony I was previously using, It’s an awesome subwoofer, and I definitely recommend it.

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.

Like others have said, it's big, loud, and heavy. My only issue is that it doesn't pair well with the XT20 bookshelf monitors. The sub's minimum lowpass frequency is 80hz, and the XT20s can go down to ~45hz. All together, the speakers end up crossing over a bit too much, and you can end up with too much bass at those "crossover" frequency, and not enough below it. Tweaking the volume on the sub only helps so much. I assume this could be fixed with an equalizer, but I'd prefer if the subs lowpass frequency could be pushed down to 50hz to better pair with the monitors in it's same product family.

Great value for the money. Built well with a stylish design. Size is perfect for our space above our equipment. Pleased with the bass performance.

It’s super muddy and lacks any kind of punch. I was hoping for chest compressions, but it just rumbles.

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!

It's a polk sub. It's quality, worth every penny and sounds fantastic. It's reaction time is one of the best I've seen and I've got a few powered subs at this point make sure you have room for it.
