Mine went up on a 3 inch thick Michigan maple block with excellent results. The block is coupled to the floor with heavy brass cones while the sub is decoupled from the block with sorbothane pads. The bass is much cleaner with better resolution but I had to adjust the sub volume up a bit to match the bass level.
Subwoofer vibration foot isolators????
I have a SVS PB13 Ultra subwoofer(piano gloss black) and the feet are rather short(roughly 1/4-1/2 inch from floor). Can anyone suggest a vibration footer to raise the sub from floor(carpet) and be able to handle my 150 pound subwoofer to eliminate unwanted vibrations of the house. I tried different placements and the vibrations decreased by leaving about 2-3feet from the walls. I would like it raised off my carpet about another 1/2 to 1 inch more...I noticed 6 threaded feet on this beast....ALSO: basement room measures 18x23. Any suggestions!!!!!!!!
