Footers under big heavy speakers (Stillpoints Ultra 5, Sistrum rack, Finite Elements,..?)

Revisiting isolation and coupling for my main system, I wonder if I would try better coupling devices than the large Symposium Svelte shelves (19"x24") I currently have under my Duntech Sovereign 2001s with 21" w x 35" d wooden base, weighing 360lbs each, which in turn rests directly onto wooden floor. My room was pretty lively before the isolation/coupling and I need better coupling/draining of energy for the speakers. 

What would you suggest?

I could try four Stillpoints Ultra 5 with base under each speaker or what I hope to be at least equally good and more economically is a pair of Sistrum rack platform (using AudioPoints 1.5) that measures 22.75"x 26.75" (I don't think their standard speaker stands can provide enough balance). I could buy a Sistrum SP-4 rack and use two platforms for my speakers. This would be budget wise the same if I would buy two Apprentice SP-SA-XL-4-1.5 (18"x24") as I am looking for a new rack for my second system (Home Theater). 

Star Sound seems to be a very reputable company but earns less coverage than, e.g. Stillpoints. 

The third and probably least talked about solution would be Finite Elements Cerabase but I find less buzz here on the Gon.

Last thing I would do is to couple the speakers to a wooden floor, as it will act as a sound board and muddy the bass. Cement floor, yes, couple them to.

For a wooden floor you need to de-couple, with some sort of heavy duty (for these speakers) Sorbothane/rubber type pads. If you do a search you will find many types around, but it will be hard for this weight speakers.


Cheers George

Cement floor couple may be good for rock but energy that goes down in cement also comes back , a disaster for symphonic strings .
Herbies composite  threaded footers solved all my problems on a 3 foot deep cement floor .

How about a Townshend Audio Seismic Podium?  You might be able to have custom built from the UK.  Not cheap, but may be the best solution.

These could be good to de-couple your beasts from that wooden sound board of a floor.

"Giant Fat Glider" or if you wish to still use your spikes. "Giant Cone/Spike Decoupling Glider"

There are many to look at.

I just ordered 6 Herbie Titanium Cone/Spike Decoupling Glider for my speakers before forking out big $$ for Stillpoints Ultra 5.  Thanks George!
