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?

I guess it depends...

If the box of your sub isn't too good meaning it physically shakes, then its better to put something heavy on top of the sub then put the monitors on top of that, mass loading. If the sub is pretty sturdy then...

you don't have to worry too much about physical vibration but mechanical vibration might or might not be an issue. Some kind of conductive cone ought to be used in this case with the pointy side down.

Do both of physical and mechanical vibrations are an issue. I think you'd know if mechanical vibration is an issue of you don't actually see the monitor vibrating while it's on top of the sub yet the sound is not right. I would imagine the speakers would sound thin and unprecise if you have mechanical vibration problems.

If neither physical or mechanical vibration is an issue, just get the dots stuff that audiobugged is suggesting.

I read somewhere that cats are great decouplers.

Slappy, The Bluedots bond really well, & you might even break a sweat trying to pull the units apart? The best thing about a pack of 25 is you might have enough left over to adhere yourself another girlfriend?

I agree. I am setting up RBH T-2P towers, and on these (and many other) speakers the monitors dock on top of the subs...

Instead of the marble slab, try putting your monitors on points (I use Audiopoints)and couple that baby to your already coupled sub. You know I'm a coupler. That may work..that's a big may, however....

Audiobugged, I like the way you think! ;)
Actually, ive been looking into some sort of a repellant. Probably due to some anomaly in the universe, girls get stupid over me pretty easily. You sure wouldnt think so if you met me though! I guess i have a natural spanish fly. I need a female Ce-coupler and a Slappy-Isolation system.

Anyways, Do the blue dots Isolate or Couple? I figured it would be best to get as little vibration to the monitors as possible from the subwoofer, but maybe im wrong and should try to get them act as a single mass?

This coupling/decoupling thing is a pain in the butt.
But the isolation cones do look cool. heheh
