In Reply to: Speaker vibration isolation. posted by jsm on January 11, 2001 at 13:31:48:
I'm using Mod Squad Soft Shoes under my KEF 104 aB stand mounted speakers. I've tried cones, blue tak, Vibrapods and Soft Shoes. I also have a suspended wooden floor. My view at the moment is that some form of isolation, eg Vibrapods, Soft Shoes, whatever is better than cones or blue tak but I do think the sound varies depending on what I do elsewhere so the fact that it works for me at present need not indicate that it will work everywhere. Now to your questions:<1. Would adding vibration isolation to the speakers likely change the sound, and if so, how?>
Improvements in focus, imaging, bass and throughout the whole frequency range, detail. Amount of improvement can vary depending on what I do under the speakers and with the stands themselves, plus vibration control elsewhere. Is it a significant enough improvement to justify cost? I'm using stuff I purchased previously for use elsewhere that was no longer in use so cost was nil. THe results are great but even at the cost of the Soft Shoes if I was buying them specifically for this use I'd be happy.
<2. Would I be better off putting the vibration absorbing material (e.g. Vibrapods) between the speaker and the stand or between the stand and the floor. I suspect it might be the later, with the speaker firmly attached to the stand, thereby effectively increasing the mass of the speaker.>
My current preference with the speakers and with gear in my rack is to move the isolation as close to the component as possible and couple as strongly as possible below that. I much prefer the Soft Shoes between the stand and the speakers.
<3. Any suggestions on good vibration absorbing material that can support this amount of weight?>
I prefer something fairly stiff. I find the speakers move too easily if bumped when I use Vibrapods but I prefer Vibrapods elsewhere. Soft Shoes are stiff and the speakers don't move much more when bumped than they do if I use blue tack. There was a post some time ago when Brian Cheney recommended pads cut from one of the auto vibration damping materials but I can't remember the name of the stuff - "Noisedamp"? Large solid protecters to stop doors damaging walls might be effective and cheap from the hardware store.
