    Boom with being boomy

    I started looking for a 12-in subwoofer to my home theatre setup. I have had my 8 inch downward firing Cerwin Vega for years. It was great for watching regular television, and movies, but when I moved my home theatre to my living during COVID, It didn't have the capacity to sufficiently fill my 20 x 18 room. I've been contemplating picking up about 12-in for a while, and boy what is it the right decision. Not only does this beast fill the room, but really provides an immersive environment. I have a 7.2 receiver, so I decided to experiment with pairing the 8 inch and 12 in together. I was fearful of it being too much and that the wife would file them papers. I was wrong. It sound way more dope than I anticipated. Watching movies Maverick and Dr. Strange and TV shows like Rings of Power was incredible. It really creates the sound envelope. If you only want or need one subwoofer, this one is a great choice. One last note is that explains well into the living room decor. It It is pretty big but, looks just like a regular piece of furniture.

    Great for smaller home theaters or apartments

    This sub is clean... within limits. My house has an upstairs landing where two of the "walls" are non existent and overlook the downstairs. With that, this sub does not get the benefit of reflection. A lot of the bass waves get lost to the great abyss that is my two story living room. So after some trial and error, I did find a place to put the sub where I do get some bass response for movies and music. It is clean bass, but not altogether as present as I would prefer. Partly because of the open layout of my small house, but I will definitely need to get a more powerful sub in the future. At least for this room. Technical babble aside, I've been watching some older movies like the original Top Gun, Saving Private Ryan, and Jurassic Park. The bass that is present is clean and accurate. This sub definitely gives me some much needed depth I've been missing from my smaller Definitive Technologies bookshelf speakers. It helps to really tie in the audio side of the experience from watching movies. On the music side, I am able to set up my newer receiver to play music to the sub as well as the speakers and it fills in nicely. But there is definitely a limit to the bass here. Anything more than half way on the volume knob of the sub and it starts getting blatty and muddy in response. It doesn't seem to want to keep up as well with music as it does with movies. I am thankful for this sub. It is good, it is clean, and I do enjoy it much more than it might sound like in this review. It has filled in a void I've been missing for a long time, especially living in apartments where I've been apprehensive about making neighbors angry. But since I have my own house now, and a lot of time to do the upgrades I want to, I will be investing in a much more powerful sub in the future and likely promoting this sub to an office or bedroom where it won't need to be turned up as loud. Maybe I need dual SVS subs for this space. We'll see. I'll need to bribe my neighbors with grilled and smoked meats before making that kind of jump in bass.

Questions & Answers

  • Does this have to be setting on the floor or can it be on top of a tableAllso does hook to the surround receiver with just speaker wire or does it take anouther cable

    Hello, the Polk Audio XT12 subwoofer has two types of inputs. LFE/Line level input and Speaker Level input. It is best to place the subwoofer on the Floor. Floor placement is highly recommended resulting in maximum performance.

  • After connecting the sub, sounds great. playing a local FM channel on the tuner, when I change inputs i.e. Roku, the sub is still playing the music from the FM channel. whats up with that?

    Hello Sam, This is an odd situation. The subwoofer will only play what it is being sent from the amp or receiver. I would recommend that you contact the manufacturer of your AVR and see what might be happening when it switches inputs but the subwoofer is stuck on the previous one.
