I have DIY speakers decoupled with separate housings for the midrange and this with the "mat" from the bass enclosure. In addition I have each quartered a "mat" and positioned at the corners. Works great! Even if it rumbles down powerful you can feel virtually no vibration at the MT-housing. A bit annoying is the fact that it takes quite stuck. One gets the parts difficult apart again, but at least residue. Apart from that, a fine thing!
