Cheap Speaker "Isolation" Solution for 300 lb. Speaker


 Good Afternoon All,

I am looking for advice on a cheap and simple isolation solution for large, heavy (325 lb. each) floorstanding speakers. 

I've read much advice on granite or marble slabs, multiple layers of cork, springs, etc; while this has been helpful, it is neither a cheap or simple solution. 

Ultimately, I am looking to protect my wood floor from damage these very heavy speakers might do, as well as decouple the speaker from the floor in order to reduce bass resonance (I am in an apartment complex and worry about noise complaints). I've looked into sorbothane pads, but they never seem to be able to hold this much weight.

Thanks!

Here's another interesting product.  Anyone tried them?  The largest version can support over 300lbs.

Let’s try this again:

The thing that is closest to equivalence of final result (of 2 Hz) when using the diamond dampers, is a precision/lab grade anti-vibration wideband safe table.

You added to my original screed, which maligned its interpretation and meaning. I said:

The thing that is closest to equivalence of final result when using the diamond dampers, is a precision/lab grade anti-vibration wideband safe table. Ie, indicating that the safe table, to compare with..should also be of a wideband nature, as in wide frequency bandwidth of isolation.

The natural tuning frequency of the dampers is 2hz. They move closer and closer to that ideal with regard to being a excellent lossy spring, as the load or mass per sq inch increases.

Which is the why of the recommendation of using a cone on the bottom of smaller lighter gear. More pressure in a smaller area, with the attendant curving in of the surface and material, toward the tip of the cone...which enables the same effect, with a lossy characteristic in multiple directions, instead of just the vertical.

If one pushes down on the corner of lets say a preamp, and the premap is on round tipped cones (read: not razor sharp), with the cone tips centered on the damping pads (large side of the cones blu-tacked to the preamp chassis), and then one lets go of the corner, they get pretty well one half cycle of motion in the preamp.

Or (to clarify), if one tries to ’bounce’ (Up-down, left-right, front-back) the preamp, in any way or any rate of acceleration, when it is on the damping pads (with said cones), they get pretty well just the single damped half cycle. (return to center)
Oh, I dunno, why try to emulate a spring when you can just use an actual spring. Springs maintain their performance and are scalable. If your diamond dampers are really so great how come LIGO doesn’t use them for isolation? 
There you go, Geoff.... purposely misrepresenting what was said. Projecting into and then calling me out on the projection. Easy now.....
