Subwoofer vibration foot isolators????

Bacardi,
Are you wanting better bass definition and as a result more resolute midrange? Is your system in the basement, carpet over concrete? Tom

Kr4 got it right.

I have an SVS PC Ultra 13 that sits on a hearth that is three layers of flagstone. I thought that placement would be appropriate. But the room still shook. Not good.

Luckily I had a set of sorbothane pucks laying around to put under my beast and it was a major tweek to improve my bass. And I don't run hot at all.

Two "subdudes" would be a good start.

To Theaudiotweak:

Yes I do want better bass definition. The bass has alot of impact and headroom,at 20HZ/100db - 8.3% distortion it is very clean output. Thus can't understand the vibration issue. Yes my system is on carpet in a basement....My soundstage is very huge past the room but it should not rattle things so much. I figured the carpet ontop of the concrete would absorb a lot to not vibrate. This sub can hit your chest hard but with tightness from its 13incher. My bass in my processor is at zero(can max at +12) and at half on back dial.....Other suggestions will help & THX ALL!!!!!!!!

Regards BACARDI

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.

For my REL Britannia B1, I have custom-made (taller, more narrow width) Black Diamond Racing Pucks with the right threading to replace the stock (plastic feet). I then have the B1 on an Adona AV45AS amp stand. This puts the front-firing driver at a good height and also allows the port on the bottom of the sub room to breath. The bass is very clean, not muddy and (has been measured) goes all the way down to the lowest frequency possible with this sub. When deep bass notes occur, they are clean, fast, super-deep and have all the impact desired. There is no shortage of bass in the approach you are looking at; here when the bass impact is felt, it is via acoustical transmission, not physical output & interaction as Kr4 notes above. FWIW...
