Hey guys, My Home theater bedroom is 15'x10' and all is well, except for the fact that my subwoofer sends a tremendous amount of vibrations through the walls so it can be heard in other rooms besides my own. This a problem for me since I am then forced by my parents to turn the volume down so they do not have to hear the sub. Is there anything I can do to dampen the vibrations. I have researched the Subdude as well as acoustic foam but with the abundance of sound absorbtion info out there I got confused and am unsure if any of that stuff will aid my problem. The speaker noise is fine since my room is well insulated its just my sub ( which i personally think is awesome, just not my parents LOL). Anyway my sub is a klipsch synergy 10 subwoofer which is complimented by klipsch quintet 3 speakers and a harmon kardon 247 reciever. Any help or advice would greatly be appreciated.
