Isolation of stacked components


Hi. I have two stand alone SS subwoofer amp/crossover units that provide power and integration of my subs wih the main speakers. These units each weigh about 35 lbs and have a foot print of 12" deep, 3" tall and 20" wide.

Currently, due to shelf space limitations, I have these two units stacked one on top of the other on the bottom shelf of one of my two Billy Bags equipment racks.

Can anyone provide a little guidance re: isloating the units both from each other and from vibrations, etc.

I use Herbie's Audio Lab products to great satisfaction for most of my other equipment. Before I went back to HAL, I wanted to get opinions/some thoughts on a starting point. Questions I have:

* Is there any value at all with isoalting sub amp/crossovers?
* Should I consider a "shelf" between the two units, such as CF shelves from BDR or Oyaide?
* For feet, is this a brass cone/CF cone application(BDR, Walker points, etc) or a poly chemical application, like HALs?

Any advice to start (including don't waste your money) is appreciated.

Thanks for the responses. Steve at HAL did suggest I try four ExtraFirm Tenderfeet under the bottom unit and four regular TenderFeet between the two units to ensure proper loading. I have had ALOT of luck with his advice and products, plus they fit in my budget. I think I will try this approach.

Any specific suggestions re: either shielding the transformers themselves or a shelf that will provide some shielding?
I have done some research on this topic and learned alot. I am getting ready to try a solutions.

Question: has anyone actually shielded the power transformer of stacked components to reduce EMI/RFI? I have found fairly easy and inexpensive solutions that involve creating a "cap" of shielding material to cover the power transformers. I do wonder if anyone can comment re: air flow and heat build-up inside the units when the power transformer has this "cap" in place.
