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?
slappy
Slappy I have your total solution. First get spikes on the bottowm of the subs and put bags of lead shoot (many) to get them almost bolted to the floor. Get a slab of wood 2" thick and get PVC pipe and glue them to the bottom of the slab in each corner. Buy 4 raquet balls and place the speakers on top of the slab and put the 4 raquet balls under the slab where the PVC meets the sub squashing down on the balls. This will give you great bass and reduce the vibration so your mids won't be smeared.

I have tried too many options and this really works, it also works perfect for amp stands. Another Agon buddy didn't thiink it would work with his Wolcott mono blocks but he now swears that he can crank it up to ear bleeding levels and when he touches the amps, no vibration.

Happy Listening and whatever else you're into!!
Mids will not be smeared because the leading edge transients will be be damped into oblivion.. unlike the real thing..Whats remains will be dark and without life..Other than that it will be okay..Tom
Dark and without life, but otherwise ok?
Heh. I dunno if i like the sound of that! :)
ummm...I guess I'm speechless on this one...looks like I'll be staying with my original setup...lol...so what's that you're saying slappy...you'll have a couple of hot psycho twins lined up for us when I get there...man...could be cool...I just got over one psycho...so I think I can hang...about the bacon though...hahahaha
