Deep and powerful bass its a large subwoofer and did i say its very easy on the eyes with the wood pattern

Great deal on this Klipsch - 12" Powered Subwoofer during the Black Friday sale. Easy to hook up to my stereo. Lots of power. I needed to turn the gain down, just below 50 percent.

Had to buy this to finish off my klipsch home theater and it makes it sound 10x better. Bought this when it was half off so that makes it even better

I had a jbl sub that was awesome! Unfortunately the power supply went out. I thought I’d try out this brand. I originally purchase the 10 inch and was blown away by the deep lows and the tight punch of the bass. But it didn’t wow me, and there were parts that at times were underwhelming. So I took it back and purchased the 12 inch. What a difference! I love it! Once I got it dialed I was happy with the deep and immersive sound it added to my movie experience. Definitely a game changer for my system. I would highly recommend it.

This bad boy produces some thunderous bass! I have it paired with a Pioneer Elite receiver and couldn’t be more pleased. Get off the ropes and buy this if you’re considering a great addition to your system. I caught a 50% off deal, but this item is well worth the full price tag. Get it, you won’t be disappointed.

Got it on sale for $300 it’s a great sub. Not mind blowing but for the price I can’t complain. I wouldn’t mind having 2 of these budget subs. It definitely gets the job done.

Incredible sound and worth the investment. Would buy again.

This sub completes my quad sub setup for my home theater system. Makes movie watching and gaming so much more impact full and immersive! The bass is impressive and makes my surround sound that much better.

Big improvements over the previous generation of reference subs. Digital amp, new speaker material, better cabinet. It’s good down to 28. Sadly doesn’t hit below that range, but good if you don’t need that.

The bass is solid, loud and consistent. I was truly impressed at sound check with the technicians. Once they install the system and I cranked it up....I could feel the bass.

This is my baby. The bass is deep and clean. Pure quality.

I've been very satisfied with this product. Great quality

I have two of these used with 2 pair of bose 901 series 6 with an emotiva xpa4 gen3 power amp to power the bose. this setup is amazing. if you turn down the bass down on the bose eq and let the subs do the work. I can't stop listening to music on Tidal. Amazing sound.

Perhaps too powerful for my townhouse basement, but it works great!

They have deep bass even with low gain. They hit hard. Movies are better than going to the movies.

Final piece of the media room for all Klipsch setup. Size and power is great with this subwoofer. Overall very happy with this one

Awesome home audio 12 inch subwoofer.. powerful and ton of non distorted bass. I love it. Window Shaker!!

Great speaker had to replace an old one this one much better great sound

This subwoofer has a nice clean sound. It was very easy to hook up and works well with my other speakers in my home theater system.

I haven't purchased from BestBuy in a while... but seeing this sub on sale got me excited. Needless to say, the sub got delivered to me the next day and it arrived in great condition. As for the sub itself, I've trusted Klipsch speakers for a long time, and this sub is no different... it can easily tremble the room. I setup corner and wall foam padding to dampen any vibrations. If you're investing in a sound system, a sub is just as important as the speaker towers and the R-121-SW II sounds fantastic. Hoping for a sale on the RP-504C II sometime soon to add it on as a center channel.
