I have had Klipsch front, center, and rear speakers for years. But I had a sub speaker box with 2 12" JBL Bass speakers, so never got the Klipsch sub. I thought my system sounded great. As a former professional bassist who worked and recorded with Grace Slick and Michael Bolton, I truly value great bass, and I thought I had it! My slave amp finally died and the 2 12" went with it. So I decided it was time to get a new sub, and I picked the Klipsch Powered 12". The moment I hit the "send" button with my order I felt maybe I had made a mistake. It isn't cheap! As an author with a published book on communication, I loved the contact I had with Best Buy. From acknowledgement to delivery, they kept me informed. I never wondered what was going on with my order. Then the driver arrived with my delivery. I was ready with my phone to take a picture of the damaged box, but it was pristine. Since I had wiring for my old equipment, hookup took seconds. Not only does it look sleek, but I have never heard better low end in a system. Music- awesome! Movies- thunderous when the action explodes. I am shocked. Wasted years not knowing I had inferior equipment are now over! It sits under an artistic display, and blends perfectly!

Beautiful sound, paired with a Sony receiver. The Sony wireless subwoofer (sw5) has good lows but on concrete it doesn’t carry well. This subwoofer does both effortlessly. The demos won’t show you want you want. You will 100% be happy with your purchase, I’ve been looking for a subwoofer for my home theater that gives you the feel of a theater experience and this definitely supplies it. Now I can finish my walls and get this flush mounted and permanent

I've been enjoying my favorite music with a whole new appreciation and being thrilled by 5.1 movie and TV show soundtracks thanks to this beauty. It's really more than what I need but was the only model available locally within my budget. I scored the Black Friday price which was well worth it for something of this amazing quality. I only have the gain at about 1/4 up on the dial but bass enthusiasts could certainly shake the whole house with this sub if they desired. Highly recommended!
