Powerful! Worth every penny; especially if you're an audiophile! The settings in the rear can be altered to fit what you want. Once I tuned them where I wanted them, I was (and am) nothing less than impressed! There is great audio quality, range of frequency, response time, and impact with every bit of audio pushed through it! I highly recommend!

I have two of these. One is dead quiet until music is pumped into it. The other? There's this 60 Hz hum, low volume, but proportional to the volume set on the back of the SW. This is without anything plugged into it. Once an amp is connected (I'm using RCA inputs), there's still that annoying hum. Pulling the panel (which holds the power supply/amplifier circuit boards), the FIRST thing you notice is the amp. board is marked R-10SW. Same amp, larger speaker in the R-12SW. And you can NOT access the power cord, the RCA jacks inside and many of the components are hot-glued in place, covered in yuge globs of unremovable pitch/glue. You can't even access the grounds. Forget about finding a SERVICE manual, Klipsch holds onto these dearly, I spent hours scouring the usual internet sources, can't even find a simple schematic. I DID however, find a manual for a similar, earlier SW which has "hum" under troubleshooting, advising replacing four large filter capacitors on each of the two boards. Yeah, about that. These components are of a brand so cheap - proprietary? - none of the three major electronics component distributors carry it and I'm hard-pressed to find specs on them. I'm told by service techs it's common for SW's to have everything glued in place. Vibration can break solder joints, damage components, electrolytic capacitors can/do act as microphones feeding back into the signal path. One solution is to use higher grade of capacitors, which I'd be happy to replace if I could get access to the boards, but they're hot-glued to the panel. Warranty? Shouldn't even be necessary. No, I haven't gone down that path - yet. I've read too many online reports of others having exactly the same issue and highly unsatisfactory factory support. On the plus side, this model was certainly cheaper than other options costing 3 or 4 times as much, and the actual audio reproduction is clearer than others I've heard for this price range, less muddled/muddied, with almost clearly musical representation of bass notes filling in a gap in performance unmet by a pair of Klipsch Synergy towers. Auto ON is a nice feature, as are options of RCA vs. digital input. Curiously, Klipsch is noted as being forward-thinking, not static in their productions. They seem to develop and market "new and improved" almost as often as I mow my lawn in the spring/summer. (intentional hyperbole here), but I'm getting the impression that one line after another has minor enough failings the factory engineers keep tinkering, altering, attempting to correct one problem after another rather than slow down, test, test some more, refine, THEN market and sell products which don't NEED support/tech help/return/repair as they're nearly bulletproof. But that, I'm sure, is why the next level market valuation for SW's is in a high 3 to 4 digit price range. After a few years' use of their products, and further review of many many blogs, forums, users reviews, endless lists of complaints about this one little issue and the nightmares owners have had to go through to resolve them, I'm no longer a fan. Pay your money and take your chances. YMMV. Read full review

incredible, brand new, great lows, shakes kitchen cabinets rooms over. i'd say 4.7/5 for power, my subs in my car are a little louder it seems, but this thing is so insanely clear. I bought a polk 10" and compared them. the polk is so awful comparitively, so much bad noise. this one hits the lowest lows. can't find anything like this for this price. shipped super fast.

Got this to replace an old JBL that gave up the amp. Happily, this is a big improvement on early tech. It turns on silently when lows are detected. It adds crisp notes that are not just a muttled boom, but strong bass music that adds greatly to the overall experience. Of course if you want to crank it up it will rattle the windows.

I already had a klipsch 12inch wireless sub that I love. This compliments it perfectly. hooked it up by itself to see if it really slammed the bass and YES it did. with both sub and the dolby atmos 625fa's the system is stunning. add a 34c center channel and a pair of rp 400's for surround and you will amaze yourself at what 2 grand sounds like.

Great Sub for a great price. Bought this open box. My old reliable Boston 12" suffered amp failure. Bought this and was really impressed with the sound and punch. Not muddy at all. My system Denon 3808ci with vr975's, 920 and vrm50's.

Klipsch.... it’s in the name, it self! I’ve owned Klipsch for years and years now, and I still love them, as if I just got them! I mean come on, first of all they’re gorgeous just to even look at!! Then I turned them on, OMG the sound is out of this world that rivals those very expensive so called high end brands..Klipsch is AMERICA 🇺🇸

Indeed awesome sauce!!! I did a huge amount of research online before I picked the Klipsch R-12 SW, and doing my homework paid off handsomely! I am extremely impressed with this sub-woofer and I highly recommend it. The build quality is excellent, the design and appearance is outstanding, but most importantly the sound and decibel level it produces is phenomenal. I couldn't be happier with the integration of this sub into my home audio and theater system. It is more than powerful enough to elevate the soundtrack to any movie or audio recording, and it's rich smooth bass is a pure delight. It's easy to set up, the controls for phase, crossover and level output allow for complete THX compliance, and it's a dream come true in returning my awesome home theater system to the level it was before. But what I think the most outstanding feature of this sub is the affordable price. I paid nearly three times as much for the Def Tech 15" sub that this SW is replacing, and it's performance is equal I believe to the strict standards I try and adhere to. This is an absolute steal in price vs performance (and appearance!) (and quality!) and again... I absolutely recommend this sub-woofer to anyone searching for clean pure power that'll knock your socks off!Read full review

Was going to get some expensive PSA's (2021 models). Found out about mini dsp 2x4hd and used to hook up 4 of these. For about $700, got same output as what would cost about $2500 from PSA. Don't go as low on hz, but sound absolutely amazing. Best I have ever heard. So glad I went this way and saved about $2000. Same output from about 25hz and up, a little less down to 20hz, still get noticeable output down to 10hz. Plus Tom at PSA was a jerk. So thankful he was and it inspired me to look around. Saved me alot, and I do not regret doing this instead at all. Remember, need mini dsp 2x4hd and REW (pretty easy to use) to balance frequencies and then they are amazing.

It sounds great. Very durable and reliable. The sub itself is awesome but amp needs more kick. It's capable of way more than it's amp pushes for sure. But overall a very good buy. I'm running it on the sub output on my pyle pd3000ba which is also a quite durable and capable preamplifier reciever. Good quality sound and crisp low end
