Isolating speakers from the floor

] but check on what weight 4 can take.

This is a good point to allow each support to works in its optimum range. Too much weigh and it is too squashed and too little weight and its barely doing its job.

For 'normal' speakers each corner would 'weigh' 16KG.

BUT for my open baffles probably 75% of the weight is concentrated on the front edge and only 25% at the rear edge.

So my calculations suggest that each front corner 'weighs' 24Kg and each rear corner 'weighs' just 8Kg. So I will probably need different front and back supports

similarly my panel speakers have much of the weight to the front edge ....The real eye opener were the townshend seismic bars ...I could place these at the appropriate points over the center of gravity. These were not cheap but the effect was as if I bought a whole new system at a fraction of the price. Al aspects of the musical presentation improved.

Incidentally there is a very good you tube presentation as to the whys and hows from townshend https://www.youtube.com/watch?v=dW9-r83IvhI

Or three pucks at the front, and one at the back?
I would get in touch with IsoAcoustics and see what they say. They usually respond fairly quickly.

I once made my own isolation pads by squeezing silicone filler into a shallow mould. I made them rectangular, about a centimetre thick and just a little bigger than the footprint of the speaker. They isolated the speakers quite well from the cavity under the floor and tamed/ tightened up boomy bass.

I have used the Townshend isolation system for many years now, and have removed them a few times just to make sure my mind isn't playing tricks with me, the diffrence with and without isnt subtle, so I can deffinately recomend those, not cheap, but IMHO well worth the investment.
