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.

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

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.

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.

Nice subwoofer, easy setup and tuning. Goes great with 800 series floor speakers

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

Bass is amazing! Definitely worth it. Will vibrate the concrete in my shop.

Love this bass speaker! It's so good it's like actually being in the theater but at home!

Not sure my neighbors love it as much as I do but dang, she works well, it’s my second one, one in the house and this one in my shop, no regrets!

Great sub for the price and its american made !!! Price i paid at outlet allowed me to get the bookshelf speakers to add to my set up

Great bass especially when using THX from AV Reciever. Vibrates the whole room when turned up and setup properly.

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

Added this subwoofer as my 2nd subwoofer to my surround system. A very noticeable improvement in sound quality. Very happy with it.

It really puts out a lot of Bass it will rattle things in your house

Amazing sound, had bought 2 subs but different brand, didn't like them so i returned them for 1 klipshe.

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.

VERY PLEASED WITH THIS SUBWOOFER THE BASS IS SOLID
