I have been using the DEFINITIVE TECHNOLOGY SUPERCUBE III SUBWOOFERS for a couple of years now, and I have to say that it has been pretty great to me. I sometimes bring it to work with me at house leveling san antonio texas. Besides one quick lag that may have been my fault, it has never defaulted. I recommend.

No negative reviews from me to provide.

Very bad experience with Definitive Technology Customer Service !!!! I bought this sub-woofer defective, and after I called, and emailed Definitive Technology, 3 calls (2 hours on hold !!! ), and 5 emails, I finally realized that when you buy product from Definitive Technology you just simple on your own. I tried to contact them for almost two weeks !!!! I would strongly suggest to stay away from all Definitive Technology products. There are plenty other good companies which will give you all support you need. Stay away from very unreliable Definitive Technology products, and very unreliable Customer Service as well !!!!

What an amazing little sub this is. It’s very sensitive to placement but if you get it right, it can put out very large pressure waves it is sublime with music. Very quick, and very deep.

Had many issues with the electronics. But to their credit, the support staff sent me what I needed.

I'm pretty surprised I'm the first person to review this sub because of it's popularity. I bought this sub to supplement bass for music. I don't use it for movies. I currently have it paired with a couple Paradigm S2 V3. Although I've upgraded speakers more than a few times over the last couple years, I've never felt the need to upgrade the Supercube III. This sub gets down to an amazing 16 Hz. What I really love about this sub is how musical it is. I can follow bass lines all the way through a song. It's always clear and tight, never boomy or bloated. It's also compact. Because It's a closed system, I doubt it will shake the pictures off the wall in a home theater application. But for hitting the low notes in music, this sub would be hard to beat. Especially for the money. i highly recommend an audition.
