Acoustic Audio PSW-12 500 Watt 12-Inch Down Firing Powered Subwoofer (Black)

2 Year Update:It's still working great. I don't use it for hours on end or turn it up loud, and have not had an issues hitting the bottom that others have. The caveat is that I have a small living room, with great acoustics. The small space and walls keep sound from spreading out but it also has a rug that keeps the sound from bouncing, so the result it a really rich and full sound. Pair that up with the sub sitting in a corner that enlarges the sweet spot and amplifies it more, and it really provides a lot of thump for a small package. Without these factors, it would be too small. It certainly is not going to work in a large living room. Would be good for a bedroom though.My other two reviews were actually before I had HDMI setup for my TV and stereo. I just recently upgraded to HDMI, and wow, soooo much better. The bass is nice and tight, cleaner and deeper. The sensitivity is easy to adjust, and the auto on/off is pretty on target now and it's pretty sensitive. I don't have to do weird settings with things like dimension and sound image on the receiver to coax out a good, clear sound.I think the bottom line, is this brand makes excellent subwoofers relative to the cost.------------------------------------Update after 8 months of regular use:I have finally gotten this sub dialed into my system and it is sounding great with daily use for music, and especially movies and shows. Until about 2 months ago, I was just not getting an optimized sound from this sub. There was a stupid setting on my Onkyo stereo that made it so the sub output would only work with the stereo's double bass mode turned on, which basically was muddying the bass a bit and a few other thing and just not has as accurate bass reproduction. Since turning it off, it has a much cleaner and I can adjust it to have a fuller bass that fills music and movies on the low end but does not overpower and muddy up the mids like was happening before. I was having to do a lot of finageling before to get it to sound good, and now it's pretty effortless. Just have to decide how low I want the bass.Also, the auto-on/off feature is very accurate now and no longer has a problem coming on when it should and at lower levels. It comes on immediately when bass kicks in in a show, and while playing music the volume does not need to be turned up to have the sub on (many times it needed to be at a level that was too loud for the desired listening experience). It also works great with the 5.1 DTS setting of my receiver.So with that being said, I have upgraded this to a full 5 stars. I am very impressed with the sound quality and richness of bass for the small package. Obviously being only 6" it's not going to shake the room, or have enough power for a large living room. Our living room is n 8" sub would probably be a little better, but as I mentioned, compactness and placing out of sight was one of the most important factors for me.... obviously I'm not an audiophile.----------------------------------------------------------------------------------------------------------------------------6 Week Update:Still very happy with this sub for the most part. I've got my system dialed in pretty well to how I want it, which is with good clear vocals and mids, and rich low end. I wish it could be a little more deep without having to turn the gain up so much that it overpowers the mids, but where it's at is a satisfactory listening experience. It tends to handle anything with a rich bass very well, such as reggae and blues. For movies and TV, I am pretty happy with it. I like my movies and shows loud, so when crank the system up, I can really feel the explosions, but I don't get to do that very much with a wife and baby in the house.The one thing I am not totally happy with is that the auto on/off feature keeps it from coming on unless I turn the volume up pretty high. Once I manually turn on the sub on at the lower sound levels, the bass does get richer, so the auto on/off is definitely hindering it at lower volumes, which is lame because if the sub is putting out any sound at all, it should be coming on, even if it's at a lower level.Other than that, the on/off feature works fine for shutting on and off. Maybe it's just my settings, since I have the receiver's decibel levels on the center channel turned way up so I can hear vocals very well and it has something to do with that. I guess I'll need to work more with this and see what can be done since leaving the subwoofer on continuously makes it get a little warm.----------------------------------------------------------------------------------------------------------------------------This a good little sub for the price. I am not sure I can give it 5 stars, but it's a solid 4+ star.In looking for a subwoofer, it was important to me to get something very small that would fit in the space created behind my corner fitting entertainment cabinet. I will gladly sacrifice some volume and deepness to keep an uncluttered living room. This fit behind the console nice and snug. There's no way I could have gotten an 8" behind it. Overall, I'm very happy with the low profile look of my system that produces really decent sound.As far as the sound quality, it definitely has a decent thump to it, but it's not going to shake the room or anything. The bass isn't as tight as I would like, but I do prefer enclosed subs to ported ones anyways, and they are almost all ported. (Gives you louder volume, less tightness). We have a fairly small living room so this has plenty of volume to fill the room up and you can also hear it well throughout our 1700 sq ft house.I primarily wanted to be able to hear vocals and dialogue well but not have tin can sound. This has rounded out the sound pretty well. I am still tweaking things constantly and I suspect that I'll need to turn down the level of the sub so that I can turn the center channel and other speakers up more, but overall it has proven pretty responsive and manageable as far as adjustments go.I did have a few small issues setting it up, although I think that was mostly related to the receiver. Some configurations in the receiver's setup didn't seem to work with this sub. The auto shut off works mostly fine for me but if the volume is not high enough, it won't come on. Not a big deal, because it has to be pretty low and at that point, you'd barely hear the sub anyways.Overall, I'm pretty happy with the purchase. I wish I could find an 8" or 10" that doesn't take up too much space, because I'd really like richer, deeper bass at lower volumes, but this definitely is adequate.

I bought this to complement some Klipsch R-14M bookshelfs on my computer.UPDATE: 4 years later and this subwoofer has had zero issues. Fills in my small bookshelfs on the computer just fine. Took rating to 5 stars because there is nothing to complain about. I see the price has gone up quite a bit in 4 years, but what hasn't in the last 4 years...2019...probably wont be a year like that for a while.In the first 10 minutes of turning it on I was already shopping for a different sub and thinking about boxing it back up. I had the volume at max and barely anything was coming out.But I decided to deal with it later and just let it play for a while. After a couple hours of music playback, the volume increased greatly as the subwoofer loosened up. I ended up turning the volume knob down to 75%. The low pass crossover knob doesn't really have any effect below about 100Hz on the indicator. But going too high will make the sub overly boomy.If you plan on being about 6-8 feet from the subwoofer, then it's an adequate subwoofer. Once you get about 10-15 feet away, a lot of the bass rolls off. Since this is under my computer desk, it makes it about 5 feet from me and it's plenty of bass for my taste.While I have never heard of Acoustic Audio, I have heard of the parent company Goldwood. I have been a Part Express customer for 20 years and they have carried Goldwood drivers that whole time. So I do have some confidence in Goldwood. I was surprised to see that the amplifier plate looks EXACTLY the same as the plate amplifier on the Dayton Audio (Parts Express brand) 10" SUB-1000. They rate their version at 100 watts RMS, where as this one is rated at 200W RMS. The Dayton number is probably more realistic. I own the Dayton 12" subwoofer and have been satisfied with that, so that makes me more confident in this brand, since they appear to be made by the same company.The competition for this subwoofer would probably be the Polk PSW-10 that is sold for a very good price here on Amazon (older generation though). It's a 10" ported design, just as this Acoustic Audio subwoofer. I ended up going with this product because the Polk is only rated for 50 watts, this model is supposedly 200 watts, but 100 watts is probably more accurate (just my guess though). Also, the reason I was shopping at all for this is because my small children have been putting all kinds of stuff inside the front facing port of the previous subwoofer I had on my computer. This model has both the subwoofer AND the port facing down to the ground. So no more random toys and items going inside the subwoofer!!!!!I did end up going with the Square Trade warranty. I was only like 6 dollars and added several years of hassle free coverage.Overall, after some break in, I am satisfied with this product. There aren't a lot of choices at the ~$100 price point. The Polk is a popular one, as is the Dayton Audio. I would consider this to be a different looking Dayton Audio that you can get delivered same day.If you are needing it for a small space and just looking for some "boom" for your small speakers, then it's a good product.BTW, the feet are about 2" tall cones that are hard plastic. With the sub firing down, you might want to get some rubber or felt bumper feet/pads to stick on the bottom if you plan on putting this on hardwood or tile. So it doesn't rattle or move around.
