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.
