  • Wall shaking.
Amazing boom and sounds great!

  • Absolutely the BEST!!
We blew up our 20 year old subwoofer almost 2 years ago. I love Klipsh and looked up many articles for the best choice. After adding the earlier version of their sub, I waited for this one. So glad I did. Changes EVERYTHING! Highly recommend!

  • Deep bass. Constant humming noise.
The bass is clean and deep! When I turn it on, I get a constant humming noise. I've tried three high quality RCA cables, but each of them produce a low humming noise. I have sub connected to the sub output on my other Klipsche speakers.

  • Awesome
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. ... show more

  • Klipsch didn’t disappoint
I use this subwoofer mainly for movies and games. I’m sure it would hit extremely hard if I pushed it but I’m not going to. I haven’t heard anything yet I didn’t like, if I did I would post.
