Isolation question. Monitor on Subwoofer


Just curious...

I have 2 subs, and due to space limits i have been thinking about going with Monitors and putting them on the subwoofers.

Here is my idea, if anyone knows if this will not work please let me know why.

Subwoofer on spikes.
On top of subwoofer either a marble or granite slab. Felt beneath the slab to keep it from scratching the top of the sub.
Monitor speakers coupled on small custom built stands (possibly built to hold sand or leadshot) to achieve the correct height, spikes on the stand which would sit on the granite above the subwoofer

Would this achieve decent isolation between the monitor and subwoofer? I see alot of speakers with built in subwoofers, or other types of speakers with the fullrange box and monitor on top, (GMA Continuims, Watt/puppy, etc)

Thoughts on this from you Coupleing/Isolation Guru's?

Would this do a decent job of isolation or should i look into other methods?

No the one on the right had eyes that were more to the south and a complexion that had slightly more contrast and texture than her counterpart to the right who had more highlights and who's edge enhancement was slightly more defined..They were the perfect couple.. or in stereo the perfect four.Or maybe that was how Quadrophonic was meant to be..Tom
The mathematicial precursor to prologic, only with better seperation.More like Dolby digital in effect..Way back in the early 70's..When the colors were more colorfull. Tom
Tom, maybe but so far in my system and a few other systems, this works for us. It is cheap and easy to find out if it works in a system.

Here is the design information on what I am offering:

Vibration robs your system of dynamics and detail, pace and general accuracy. It is everywhere even when your speakers are not creating their own and feeding it back to your equipment via your floor. The system-external sources are ever present and both naturally (geologically) and artificially created, and only vary in intensity throughout the day. Low frequency noise exists at all times in our modern environment, and in all planes, not just the horizontal or just the vertical, passing through the ground and building structures easily.

The design is a vibration isolation system to replace the existing spikes and cones that normally come with racks, stands and other bases, as a matter of current style. In simplistic terms, the idea is basically retainer cups with a rubber ball placed under them to isolate from vibration in all directions, unlike many devices that only work in one plane. Simple, yes, but this is a true pneumatic suspension. Many other devices are meant to “shift” resonance (thereby fooling the buyer into thinking that something good has happened temporarily until the listener realizes that the noises only moved a bit in frequency). Devices touted to “ground vibration” to somewhere, usually the shelf or floor they are on, “work” in that fashion. This cannot work well, as more noise comes from those than can possibly be passed to them! Spikes and cones can only be couplers, never isolators. That means that they actually help noise up right into your stands and everything on them. They cannot be “mechanical diodes”, the totally incorrect “new wives tale” most of us have seen parroted somewhere. This is a seriously misunderstood thing presently. The design is simply and more straightforwardly meant block them altogether, within the limits of performance that still allow this device to be sturdy enough to support heavy equipment, and they don't poke holes into your floor, either.

Hope this is helpful.
