My current subwoofer is not working right now(waiting for a new replacement AMP to ship from Klipsch), so I currently set my front speakers to large, and I gotta say my speakers gush out some pretty good bass. Of course a subwoofer will always be better, but damm I gotta admit i was impressed. My front speakers are tuned port bass reflex. 15' woofer, with a mid-range, and tweeter. I bought this set back in 1993, and their still going strong. I had the woofers reconed back in 2008. I'm using the speaker system with the Pioneer VSX-33.

Well I gave klipsch a call this morning, and I must say I am very very pleased with their customer service/tech support. The rep was very knowledgable and thorough. Their shipping me out a brand new replacement AMP for about $112. Definitely cheaper than buying a whole new sub. According to the rep it's a pretty simple replacement process, basically 10 screws to remove and then from there it's just plug and play. I'll keep you guys posted. Thanks.

So did I....... But after reading several threads and the many subwoofer issues people are having, especially with the amps, I'm a little hestitant to try klipsch again. Also I've already read a complaint about the SW-450 on here, so I don't know about that one. I don't think I will go used, especially with Klipsch. I love the smell and taste of new lol. i'm gonna give Klipsch a call and see about maybe getting a replacement amp, that's if they still make it for that model. Maybe I could use a different amp, if klipsch can't provide me the same one? Aftermarket possibly? Appreciate all the advice.

Well it's a short lived celebration.....[] It started actually last week, when the bass suddenly became anemic, but it then came back strong, and now as of today it's acting weird. In the beginnining it was anemic, but now it kind works sporadically and it sounds crappy when it does. Odds are it will start working properly again, but by that time I will have thrown it out the window. I'll probably pop it open like you guys suggested, and see if there is any loose connections, but I'm at the point of being tired of this piece s h i t, sorry had to rant. Are the new Klipsh subs a lot more reliable? If I can't get this fixed, I'll probably buy a new one, but I am not sure if I am gonna get klipsh again. What do you guys think of the klipsh SW-450 subwoofer? Anybody have any experience with it? Thanks DRC72

Well comparing the new cable with the old cable, I could see a big difference in build quality. The monster cable was much more beefier, plus I would bet it was shielded better as well. Regardless I'm keeping my eye on the sub for the next few months just to be 100%, but I think i will be fine.

Well so far so good! Looks like my previous wire was bad. I'm 99% convinced, but there's 1% that I still worry about. Regardless I'm glad it's working, because this bad boy pumps out deep bass, and I would hate to lose it lol.

UPDATE: Well it might be a wire issue after all, but I'm not 100% sure on that. Anyways the first wire I purchased was not for subwoofers(clueless sales rep BB), so I returned that. Now I picked up the Monster ultra 600 THX subwoofer cable, and so far the subwoofer has been coming alive each time I turn it on. I don't even have to wait for it to come alive any more. Granted I am not 100% convinced, and the sub could decide to stop working again, but I am keeping my fingers crossed. Have you guys ever seen SW wires go bad? One more thing, I'm also using a Y connecter that came with my monster cable. It's connected to the L and R RCA jacks of my sub. I'm not sure exactly how much of a difference it is making. I'll keep you guys posted. thanks for the help. DRC72

Are these boxes easy to get into? And when you mean driver, do you mean the woofer itself?Thanks for help.

UPDATE: Alright I tried replacing the wire and I got the same result last night, so I can rule that out..... Anyways I checked it again this morning using my satelite reciever which outputs Dolby Digital in a lot of their channels. As usual the bass was anemic to none, so I popped in a blu-ray that I know has a strong LFE track and as usual the bass was anemic. So I fast forwarded to a part of the movie that has the strongest bass output(the LFE track on this movie is very strong), and a huge pop comes on and the bass is roaring again. Now the funny part is I returned back to satellite, and continued watching the same broadcast earlier. Guess what? The sub decides to continue to output strong bass on satellite. It's almost like you have to work it hard to actually come alive. Now the funny part is it might decide to work the next few days, and then it will get anemic at some point again. It's mind boggling. I love the klipsch sound, but I don't think I'll ever buy a subwoofer from them again. It's to flaky.

Good point, no not yet, but I will give that a try,. But from what I am reading on here it looks others have experienced the same issue with the amp failing. Thanks

I know I am bumping up a really old thread, but my KSW-12 is reacting the same way. At times it will rock the house and at other times it is very anemic or it just doesn't do anything. I've tested the sub on material that I know will have strong bass, and it's just not responsive anymore on that material. I take it that the amp in the unit is failing? I know my unit is old, but any help would be greatly appreciated. I've used the sub on two different recievers. In the beginning of the problems, it seemed like the sub needed to warm up a little before the hard bass kicked in, now it's pretty much a paperweight with a red light, with a barely responsive woofer.HELP!!! Do I need to buy a new subwoofer? DRC72
