Along the lines of what Marty has said, I always thought that the key was to place cones/points under the areas of the component which are most vulnerable to vibrational effects FIRST, then distribute the other one or two to provide balance and overall stability.
3 or 4 cones under speakers /cdp which better WHY
Most cones come in sets of three but some also come in sets of four . Whats the lowdown on cones I am thinkg of trying tem under my speakers and CD player . Thanks for your time!
