How accurate is this description of isolating speakers ? I don't have any anti-vibration foam but I did find some spare non-slip mat (soft rubber). I used two layers for my Klipsch rp-600m(mounted on my computer desk).
For me, it made a difference in the base response (louder, more precise) , not so much for highs/mids. I had no idea these speakers respond well to anti-vibration pads.
