I used the Gramma's under my last speakers because my wood floors were acting as a giant subwoofer. I would put my ear close to the floor 10 feet from my speakers and here bass coming from the floor, even with a huge Oriental rug in front of the speakers. The speakers were on the wood floor though.
They worked absolute wonders. I sold those speakers, gave a Gramma to my wannabe rock star brother in law (who loves it, especially for raised stages) and have one left that I'll probably sell. I bought mine at Guitar Center.
