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, "She sure seemed human untill she go me home"?
What the heck, are you typing in tounges? Boy she musta hurt you bad! You better lather on the Ben-Gay, prior to your next encounter!
Yeah, next time i will be sure to arrive in full hockey goalie gear with a baseball bat and a can of mace! (laugh)
Slappy, Full Combat Gear, wow that makes for a SCARY visual! LOL
No wonder your looking to isolate, prior to swinging your Bat.
Slappy,
One more idea: Any stainless fishing line ?
Suspend and cradle monitors from ceiling 'just above' the subs ?
Just an after thought bud, sorta like the levitating act.
Yeah, as Rx8Man suggests Spectra-Line might be a good choice. It doubles well as an assassination wire like in Marathon Man.

The other thing I'm thinking is that even if the sub and monitors aren't touching, but still in very close proximity, the massive movement of the sub's driver may have an effect on the movement of the monitor's woofer. It might affect the midrange.

The reason I bring this up is that I've had a couple experiences WAY in the past and fairly recently where a monitor's woofer affected a passive slave sub's driver.

So Slappy, you've got yourself slaves, subs, straddling, fishing line and hot psycho chicks. Why are you still here with us?!!!
