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!!!!!!!!

Great Gramma or similar Auralex platforms.

I recommend you contact sound anchors to make you a custom stand. Not expensive, high quality and will exceed any footers you meet purchase. Send him the speakers dimensions and get an estimate.

Don't you want the sub coupled to the floor? Putting it on isolation feet will muddy the bass. It should shake the house, not the other way around. For that matter, with carpet I would consider spikes and sand bags on top. Yes, keep it away from the walls a little. Just my 2 cents...

If you want it to shake the house, it should do so, when appropriate, via the acoustical output, not via physical transmission from the sub enclosure to the floor.

OTOH, I do not want the sounds of my room or its contents contributing to the sound of the performance. Thus, either way, isolation devices can help.
