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?

@avanti1960 - I am so sorry, I didn't really look at the year.
It's an old and long dead thread. Excuse me.

Actually it's not entirely without merit, using springs and the substrate to isolate both the tops and the bottoms. We've seen many smaller speakers placed on top of sub boxes, but to really isolate them extremely well??

I think there's a better way, using something like I've discussed here. Suspend the stand mounts above the subs, which are also isolated on springs.
Then have another two matching subs elsewhere in the room, as a DBA, they will match the looks, it's an interesting proposition, don't you think?
Well Rick and Miller I still stand by my advice that I gave to Slappy 17 years..the Sistrum and Audiopoints are still most effective. Tom
Again, you are invited to show us at the "gathering".
I'll be the first to admit I am a budget driven audiophile, when offered something triple or more the cost - it had better deliver better performance.

At least two of us are on board for technologies that produce better performance, such as isolation devices, or vibration control devices, whichever way you slice it, superior engineering practices used for the purpose of playback.

We are aware these aren't just superficial tweaks, these are as substantial as swapping into magnetic ride suspension from leaf springs.

I would like you to be proven right, you are passionate about the product, and I know it's a long way, however I'd like to know??
Can you have your stuff shipped? I will meet you half way, I'll pay for return shipping, in the exact shipping materials you send them in.
I tried some lower end stuff, and I returned them without fail, this is a friendly challenge, you're not being ignored. However there is a standard that is making headway, Townshend has been selling from reports in the forum.

If your technology is indeed superior, are you certain you don't want it known?
It will be a toe to toe match, no mistake, we'll be very open with our opinions on everything we hear, across the board.
