Hello, I just moved to japan with my wife. We are currently getting everything ready for our home theater setup. My question is that We bought a HTiB minus the dvd player. Because we already have a region 2 and region 1 dvd player. We went with the Denon DHT 300dv-s. We tested this system in the store and where shocked by the sound that came out of this little system. Although it was no where near as powerful as the system we had back in the states. Anyways my question goes like this. Is there anyways of saving the people that live under us from the bass from the sub. As far as putting something under the sub. We have all wood floors in the living room. Anyways that is my only question, thanks in advance.
