I have owned the Klipsch R-12wi (wireless version) for about a year now. The unit is still fully functional and performs as well as it did when I first purchased it. It performs to its specs, nothing more nothing less.

When I first purchased this it was my first subwoofer so I was very impressed with the power it was able to put out, but as I expanded my musical listening I began to find its frequency response severely disappointing being 30hz @ +/-3dB. When only listening to tracks within its range it is powerful and performs well, but it doesn't have a low enough extension for me personally. The roll-off slope also seems to be rather high. If I listen to a track that has many notes alternating closely below and above 30hz the track will sound "floppy" due to notes below 30hz just dropping out .

None of my issues are the fault of the subwoofer however. The product performs exactly as it should, so why not more stars? Because for the price and form-factor there are better and more robust options. The subwoofers job should be to extend the range of your speakers. If you already have decent speakers than this subwoofer will not extend their range much at all, and if it does it would be less than an octave. This is especially true if you have floor standing speakers since many can already reliably reach 40-50hz. I'm using the Klipsch RP-150M bookshelf speakers and they respond well even at 60Hz.

If you do not listen to many bass heavy tracks, or have small speakers than this wouldn't be a bad bargain. However, if you already have decent speakers and are really trying to fill out the low end I would pass on this and look elsewhere.

These go on sale as cheap as $275. Right now the bargain is the 10 WI. Watch for sales. Woofers go from Polk to Bic to Klipsch to SVS. If I could afford 800 bucks for a woofer that's what I would get. Little woofers like an 8 or 10 will work for movies but for music I need 12 or bigger. My 2.1 is not right left and subwoofer it's Robert Jimmy and John. Towers should be six and a half or a bigger. Try focal or Klipsch or elac you could start with these klipsch rf 62 ii and go up (or SVS 2 for $1000) try setting the gain at 3 o clock and running the cal on the receiver and use that for movies and put it back to 12 o clock for music and adjust to taste

I have a Pioneer VSX"“82TXS 7.1 receiver (130 watts) configured as 5.1 originally driving JBL Venue series speakers (the large Stadium fronts, etc) along with their Sub12. Recently the subwoofer started making odd sounds and a burning circuit board smell permeated the room. Can't live without a subwoofer, so time to look around.

Read lots of reviews everywhere and finally settled on getting the Klipsch R-12SW. I've had it now for just shy of a month and am absolutely amazed at how well it performs, especially as compared to the old JBL. It has a MUCH richer and broader response and simply sounds as close to perfect as you would want. I can't get enough of how much it adds to music and movies. We have it in our living room and I can stand in our kitchen/dining room some 35' away and feel our hardwood floors vibrating at only a moderate volume.

Love it and highly recommend it.

My first Klipsch product..and I've longed to own their stuff for years. This is one heck of a great sub! As with any subwoofer, careful tuning to match the rest of the system is required, and after a phone call to Klipsch tech support, a 24 hour break in period doesn't hurt either. That is, 24 hours of moderate to low volume use to loosen the surround before really cranking it up. Klipsch has long been known for their incredibly efficient speakers, which means they can play louder with less, and this sub is case in point. After all of the tuning and adjusting levels, I was pleasantly surprised and how this monster is a highly musical subwoofer if tuned properly, and adds weight, scale, and muscle to any music I give it. Its class D amp (digital) at 200 watts RMS, and 400 peak, allows for it to be lighter, and create less internal heat. It effortlessly pressurized my listening room with power in reserve...for under $500 you can't beat this one...

Purchased to replace two Polk 10" sub-woofers I had previously, amazed by the new impact and spl in <40hz regions. Over the past few nights of movie watching I've found myself continuing to turn them down, currently low passed at 60hz these have a lot of power to spare. One the best powered subwoofers in the price range, clean, powerful, gets low. I'm using 2 of them in an approximately 500 sq/ft room as part of a 5.1 system using large towers as my fronts and rears, there is room for growth as the subs are not being pushed hard which will be great as I move back into reference amplifiers for the main speakers. I have a wide variety of musical tastes, classical, rock, metal, edm, rap, country, and much more they do it all well.
