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.

**** 3year update ****3 years now....daily use....over 3000 hours now per my averaging. Still impressed, in a 20ft by 20ft by 24ft space, but then open to the rest of the house beyond that. In the time since my original review below, my Velodyne HGS-18 in the theater room has blown it’s amp, sadly....but this little 10” acoustic audio continues to play well in our living room... 3000+ hours in now. Zero regrets!**** original, one year review ****I never have come back and written a review a year after I purchased a product. Today, while playing some music while cleaning the house, what I was hearing from this, now one year old subwoofer, compelled me to post a review of this product.A year ago, probably much like you, I was in the market for a small / moderate subwoofer to cover the low end for my living room TV setup. We got a new 4K TV, all of which are flat, and this one with the speakers on the back. Its hard to hear things, I think some kind of soundbar or stereo setup is required to be able to hear anything properly. I went the stereo route, as I already had some Klipsch “satellite” monitors mounted high in the 4 corners of the room. The room is terrible as far as size / shape. 20 ft x 20 ft with 24 ft ceilings, but its also open to EVERYTHING. Its virtually impossible to get awesome sound in such an environment, so I was looking for something good, but didn’t want to break the bank on performance that would be lost in such a terrible environment for sound.I picked this little sub up to hide away in our living room setup. Its tucked away, and nobody can really see it. 10” downward firing driver, down firing slot port, and the amp is rated at 200 watts continuous and 400 watts peak. Well get to the amp ratings later.I have to say….this thing is great! Has been from day 1, and we are at day 360+ of constant…DAILY… use! Truly, it sees use for hours, every single day, as this is the room where my family spends the most time. I got it for TV sound, as the small Klipsch satellite speakers mounted 12 feet up couldn’t possibly even cover any kind of bass. This sub has exceeded my expectations. It’s truly awesome for movies as well as standard TV. A nice big impact all around. And when you consider the price, wow! The price / performance ratio is outrageous. There is full bass, throughout the room. It’s not hollow sounding, it’s nice and full and deep! It sounds spectacular! Today, while playing music, I was overwhelmed with how great it mixed and filled the room, and sounded nice even in all the other adjacent rooms, it really made the music sound spectacular. Not only good for TV and movies, but music too!Now, some naysayers may say that such a low end system means I don’t know what a good subwoofer should sound like. I don’t believe that to be the case. I have a room my family uses as a dedicated theater. It’s the perfect rectangular shape, with 10 foot ceilings, and no windows. Acoustically treated, and calibrated. It has some modern components, including a full 7.2.4 Dolby Atmos and DTS-X processor and speaker setup. One of the subwoofers in that room is the Velodyne HGS-18 series II subwoofer. It has a servo controlled 18” driver. 1250 watts continuous / 3000 watts peak. Its massive, could double as an end table, 120 pounds….and THX certified to boot. It plays down to 5 Hz, and is simply devastating. Despite its age, to date, Its still regarded as one of the very best subwoofers made for the consumer market. I’ve included a picture of the two together - the under side of the Acoustic Audio 10”, and the front of the Velodyne 18”, to show how much smaller the acoustic audio is, it will tuck away in any room very nicely. In the dedicated theater room, I don’t care how big it is….the room is more functional than beautiful. I don’t want that in the living room however! The Acoustic Audio 10” is perfectly small, and can tuck away nicely.In no way am I here to compare the abilities of the Acoustic Audio to the Velodyne. Its no competition, its also not the intended competition I suspect. The Acoustic Audio isn’t meant to be able to recreate the sonic output of an earthquake….the Velodyne is. However, the Velodyne was also 30 TIMES the cost of this Acoustic Audio 10”!If you aren’t expecting gut curling bass that can shake the walls, but rather a nice powerful low end that can play deep audibly, dynamic and musical at the same time, works equally well at video and music programing – I think it’s difficult to find a better consumer subwoofer at this price point for the performance that it delivers. This small package does a fantastic job filling such an odd and large space with very pleasing and at times surprisingly powerful performance. There are people that are critical of the amplifier in the Acoustic Audio 10”. Rated at 200 continuous / 400 peak, they say in actuality, the amp is way smaller. I honestly can’t say, I have no way of measuring….I have to go on how it performs, what it sounds like. And on that front, if this thing only has a 50 watt amplifier, whatever it really measures at…its working….its filling a very big room with generous and powerful bass….and remember how much $$$ we are talking here.1 year in….and without a doubt, all thumbs up – BUY IT!
