I just recently upgraded my HDTV to a Sony 75 (luv it - thank you BB) which led me to re-evaluate my home theater components. I have Klipsch fronts and center speakers that I am very happy with. But my two Yamaha 10 inch subs just didn't seem to have that deep punch in your chest feeling that many reviewers here have mentioned. I listened to the DefTech subs that are setup in the Magnolia room, which were played with other Deftech speakers that also have SWs in them. Not exactly a level playing field when you are trying to evaluate a single sub. My research indicated mixed, but generally satisfied reviews for the DTs, but they come with a bit of a premium in price that I wasn't sure I could justify, at least not before I tried the Klipsch subs. BB actually keeps their Klipsch speakers in the cheap seat section, sandwiched between two isle shelves about 4 feet apart. It's nothing like their Magnolia room setup. IMO this is an injustice to a brand that is so highly regarded and has generated many millions, I am sure, for BB. JMO. So, it really leaves no choice but to buy and try, which BB is really good for and I only live a few miles away. So, away I go with my Klipsch 12 SW after work one night. Had to get it right out of the box (wife said I had that little boy at Xmas look on my face :) ), hook it up, plug it in and play the best available action movie I could get my hands on. There really wasn't much to the setup - low pass filter - turn to max per manual, volume-turn to about 1/4, and a couple of other de minimus settings. I chose, what else, but a war movie and sat back to wait for the explosion scenes. And let me tell you, I got punched right in the chest with every artillery shell that landed. Plenty of bass and then some, way more than my two 10 inch Yamaha subs could ever produce. It also produces crisp, responsive bass for music. I really got into listening to the bass player on a number of tunes. I was holding out the possibility of adding a second sub, but that would def be overkill and would make the table I would have to put it under sing too much. My room is 15 x 21 with an open floor plan to the kitchen and I noted some concern about this with the DefTech SW reviewers. I can tell you, hands down, this sub is plenty for my space. I think it would be overkill for a small apartment, though. I keep it at about the 1/4 mark and adjust the volume from my AVR remote. This time out, with some extra coin to spend for a premium brand, Magnolia Room-snooty SW, I found that spending more doesn't necessarily mean getting more. The price point for this item is substantially below the Mag room competition and IMO performed as good, if not better than the DTs. Also, the reviews on this item have been overall stellar from BB, Amazon and Crutchfield customers. For price and quality, Klipsch is hard to beat. I'm very happy with this item.
