KlipschReference R-121SW 12” Front-Firing Subwoofer with revamped Spun-Copper thermoformed crystalline Polymer woofers and an All-Digital Amplifier for Premium Sound in Black

I don't have the world's best back so the light weight of this subwoofer relative to its size and performance was appealing. It has good extension and can reproduce quite low frequencies, though its EQ has a hump at about 55hz. You can EQ that out or just enjoy it, nobody is going to make you stop! Group delay is good for its size and rear-ported construction as well, better even than some vaunted performers in its on sale price range. Ample dynamic range for cinematic low frequencies and when dialed in, it has a lively and relatively quick low frequency reinforcement for music as well. I pair mine with Klipsch RP-600m (first gen, love them) and set the crossover to reinforce from about 60hz down.Its loudness has been more than enough for my space, it can overwhelm the living room it is in when movies rumble! Feel it moving that low low air into the kitchen and other rooms even. But, to be maximally fair, if you are in a very large room you might want to consider a larger diameter speaker model or perhaps a higher output unit. I've had zero complaints about it's output but it is somewhat conservative compared to the Reference Premiere subs and some competitors, and it has rock solid DSP limiting that stops it from exceeding its capabilities. In my personal use even with bass impact action films I have not met its limits!

Purchased to complement my Klipsch Reference Premiere RP-8000F II speakers. I live in an 850sq apartment and this sub is MORE than adequate. Dare I say, it to big??Frequency range is 28Hz - 120Hz.Bass is clean, clear and LOUD. (if you want it to be) It sounds so good, it almost rattled my teeth out. You can actually feel the bass. It sounds amazing especially movies in 5.1 surround sound with this speaker and sub combo!!! Metal and rock music sound AMAZING, house music when the beat drops is awe inspiring! I wish the frequency went a little lower to 20Hz but I'm +50 and doubt I could hear that low anyway. lolFew things in life are worth every penny you paid for them and this sub is one of them. Puts a big smile on my face every time I fire my sound system up.

There for about 30 seconds, I was very un-impressed, but then, the movie played a bass sound and WOW! Talk about DEEP, room feeling lows. I’m newer to the home audio game, but I have extensive live audio experience from a “past life.” This woofer feels the room and caries the low end punch that I only could’ve dreamed about in a live venue. It’s definitely tuned beter for tv compared to music, but it still does wonders for music. I recommend the purchase to anyone who doesn’t prefer to listen to boring, dull, flat sounding music like what came from your neighbors busted Sony in the 70s.

I got this to round out the Klipsch set I bought from Costco. Very nice. The brass cone presentation is fire.

This is a great subwoofer. You will love the sound. I am glad I invested in this unit for my stereo.

The media could not be loaded. The subwoofer sounds great, deep clear bass. I have 2-12” it never distorts I can hear and feel the perfect balance in between the two.The look of this subwoofers is so beautiful and the build quality is amazing, worth trying. I’m sure you’ll enjoy it too.

Subwoofer produces loud, deep, undistorted bass. Couldn't be happier with the sound, just two small complaints. It is quite large but also has a nice aesthetic to combat this so not much to complain about here. Second is that mine did not come with a rca cable. Luckily I had one to my existing 10" woofer, but still. Couldn't hurt Klipsch bottom line that much to throw in a basic rca connection cable.
