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?

Is not that what Slim Pickens yelled as he rode the A-bomb down from the sky to its final destination in the pro humanity movie Dr.Strangelove..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
If you use Audiopoints, and I feel you should, then do not combine coupling with so called isolation..to do so would be the worst of combinations..The Audiopoints are designed to be directional..the point has a bandpass of 2hz to several meg..So you want to use Audiopoint 1.5's or 2.0's under the subs..On top of the subs you would then place 3 Audiopoint APCD coupling discs which impove point coupling on wooden surfaces and also protect the finish. Now you want to place, point down into the dimple of the discs Audiopoint 1.0's or 1.5's so your speakers sit atop the flat surface of the Audiopoints..This arrangement allows for a single exit point for the relief of vibration..You also have the benefit of wave launch enhancement..because you now have the possibilty of aligning the voice coils of the monitors with those of the subs below..You can carefully slide the monitor front to back on top of the sub..The APCD discs allow you to do this tweak easily..careful how you push.. you can knock the point out of the dimple..I have performed this procedure with several subs and monitors..Including my Servo15's..Someone mentioned marble atop a speaker that used some other type of points..doing so would slow down the possible exit path thru the point and provide a different exit speed thru the top of the speaker.Resulting in confusion...Tom .I am a Starsound dealer
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
I think they were hired to entertain the troops at a booth at the Cedia AV show and clubs to the northeast of downtown Indianapolis just last weekend..Thats what I saw and I think I remember..They shared the same chair and were friendly with each other and anyone else for that matter...Tom
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
Peter thanks for the info. What works in our own separate worlds and experience is the most correct one at that portion of time. For you to stop at this point of time and with your open mindedness and desire for further knowledge on this particular subject would be a waste. Some of the products and techniques I have mentioned here so many times before, I feel are fundamental to the music. What I am a proponent of increases the efficiencey of any electro or mechanical device sitting on the platform or point.I have measured this acoustic gain..The detail, the gain in dynamic contrasts, the stage size, the focus all become more apparent,separate yet whole....Coherent and correct..I can tell you from the heart and the ear, isolation is not the key to the enhancement of the musical source.I can tell you there are exciting enhancements to the source that I have measured, recorded and photographed that will come to light in the next year..Tom
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
