Speaker shock absorbers

Ssglx - I use 5s under front and 4s under rear. I remember from their website that it's better to use few of the low number instead of one of the higher number. I consider putting speakers back on the spikes on oversized granite slab/tile and a lot of #1 vibrapods between tile and the floor. Equaracks might provide better stability and better damping characteristic. I don't mind spending more on non-perishable items like cables or footers.

Interesting thread.

My 150 lb speakers are on spike, but instead of sitting on carpet directly I found the sound to be better sitting on a 1/2" granite between spike and carpet. I used the granite which was left over from my house remodel for ease of moving the speakers initially, but after hearing what they do I left them under the speakers.

I am ready to try something like Symposium platform under the speakers, but I agree spikes should still be used regardless what you put under.

This is a bit older thread, but I thought I'd report some successful findings.

A few months ago I aquired a pair of Soliloquy 5.3i floorstanders. Great speakers! I'd been trying several types of footers to get the best balance, musicality, clarity, and bass.
With my older Soliloquy monitors it was no contest. Vibrapods hands down for clarity and great tone, exceptional liveliness, and even a little bass boost and growl.
With the floorstanders I tried several variations of vibrapods, different configurations and ratings (#4's and #5's). I got the clarity, tone and musicality I wanted, but the bass was always just a step behind the music and a little sloppy.
Another product I'd tried with the monitors are a cork and rubber product called Isol-Pads available here on Audiogon. They did a good job of decoupling the monitors but lightened the bass unacceptably. On the floorstanders however they have been great! Clarity is still good, the sound is very clean and musical and now the PRAT is back. Bass is appropriately quick and even, and still with satisfying weight. Low level liveliness is good, much better than on spikes, but not quite up to the more energy preserving vibrapods.
I would encourage anyone who wants to try decoupling their floorstanders to try the Isol-pad product. They are not at all expensive.

Try Herbie's Tenderfeet or the bigger Tenderfoots.
Herbies Audio Labs.

I have never tried these, but...Meade and other telescope manufacturers make isolation pads designed to go under tripod feet, sold in 3 piece sets.
Lots of industrial isolation pads available if you google.
