Klipsch R12SW 12" 400-Watt Powered Subwoofer

Great sound, got it on sale @ [price]. Replace my Velodyne 12 inch. The only thinks is the cabinet is cheap and press board other then that its sound great

  • from Ottawa, ON

great subwoofer

my previous subwoofer never seemed to sync with my Marantz system amp so I got this Klipsch R12SW 12" Subwoofer and once I did the Audyssey automatic sound set up with the new subwoofer, it sounds beautiful. I may have to turn it down with the Gain adjustment on the Klipsch but very happy with the sound. I like the auto turn off after 15 min of inactivity too.

Highly recommended

I bought this 12" to replace an Infinity sub of the same size that failed with that annoying crackling in the transformer inside the enclosure. Sound wise sounds just as good as the defunct Infinity; my only peeve would be the enclosure itself that feels plastic-y compared to the wooden one from the Infinity. And since its the sound and depth of bass that counts, it has 5 stars from me.

12" Klipsch

Great addition to any audi system. Superior lows, great frequency response Incredible power out put! Input is turned all the way down!

Amazing once you know how to set it up

Couldn't ask for more in a sub-woofer, solid clean base and appealing aesthetics - you may have to play with placement in the room to avoid boominess and muddled sound while also ensuring that you follow set up instructions as required by your receiver so that you get the best sound out of the sub. (LFE vs RCA input). I use my receiver to control all the crossover settings so the sub crossover is currently set at the highest possible setting and the gain is about midway - sound is awesome (tip: you may want to use your receiver calibration mic to ensure the sound is balanced and in tune with your other speakers based on your usual sitting positions) I think i'll get 2
