Great Sub. Fills the room with great warm sound and gives amazing depth to bass in movies and music.

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.

Have great experience listening to music and watching movies. Fills the whole living room

Awesome sound great price for the unit Looks good too !

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

For the Black Friday pricing of $299 this sub is a steal, had to find a replacement for my old Polk that finally died, this thing is much more powerful than it and provides some good LFE/Bass.

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.

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.

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

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.

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.

First time purchasing Klipsch speaker even though I've always know it was good quality sound. This 12" subwoofer got a good thump to it and takes care of the bottom sound with class. And what's great is I caught this 'Bad Boy' on a great Cyber Monday sale.

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

This subwoofer took my home theater system to another level!!! even watching commercials, boom baby!!!

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

I have been watching this online. I had it in mind i should try , it was beyond my imagination when i tried. Punchier bass with clarity . I can recommend

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 have this in a bedroom converted to a media room, so not a large room.....man does this thing absolutely DUMP! There isn't a safe place in the room, and I love it HA! Makes my body rumble like I am in the action. Don't sleep on this if it is on sale. Unless you find the SVS SB100 pro at a similar price, this is the mid-level sub at a low-level price you need.

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.

I would rate it 4.5/5 if I could. The Klipsch Reference Series 12" sub provides ample bass, a bit boomy, but it can be dialed in to fit the space/speakers to which it is paired. From a purely conic standpoint, it is 4/5, but the value for money gives it an additional 0.5 stars for a total of 4.5. I paired it with my Wharfedale Elysian 2's and it really has filled out the lower frequencies that I was missing in my space.
