Great big bang for the buck!

I have two R-121SW subs filling in all my bass in my 7.2 theater room setup. These subs sound amazing and easily rattle the entire house. In fact, the gains are not even at half volume! They’re a great big bang for the buck with great quality sound!

Excellent

I bought the R-50PM + R-121SW combo and was well worth it. I fully enjoy the way it sounds.

Klipsh Rock

I’ve been Rocking a pair of Fortee II’s since 88 and added not only a pair of these bad boys but also added the rest of the top of the line Reference Premium Surround pieces to complete 7.2 surround sound, simply amazing.

Good for the price.

Great sub, compared it to a sealed SVS SB-1000 in store and was impressed. I thought the sound from the 121 was much cleaner. It may not hit the same lows but is a powerful unit. I recommend the 121 over the 120SW or SWi as it has higher RMS. Great purchase if you can find it on sale.

How did I go so long without a subwoofer?

This is my first subwoofer. Bass for days. Can thump the house for hip hop. Still sounds great when turned down. Renders instrumental bass very well

Satisfied, not in love

I have been a Klipsch fan my whole life and have not owned a set of Klipsch speakers for over 15 years. I have been looking forward to upgrading my system for as long and was not disappointed. We went from an LG sound bar for the TV and Bose tabletop speakers for the turn table both with small subwoofers to the R-121SW paired with two RP-8000F IIs. We love the RP's and I was hesitant to get a large subwoofer with the RP's frequency range being so large, but I landed on this since it was on sale. I am satisfied with the purchase, but the R-121SW lacks the power and clarity that former Klipsch subwoofers that I have owned and listened too.
