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.

There's a guy selling stillpoints component stands on agon for a pretty good deal right now.  

I have those under my exemplar horns to good effect.

Can add ultra 5s to the component stands down the line and basically get the equivalent of ultra 6s for my speakers. :)

Depends what you are trying to do.  The suspended wood floor can complicate things, and may require decoupling for the best result.
With my carpet over concrete floor, I try for as solid a base as possible for my 100+ pound speakers, and I like edenSound Bearpaws under custom Sound Anchor stands that are coupled directly to the speaker.

Suspended floor. Magico Q5's, over 400lbs each, Stillpoints ultra 5's. Great looking. Easier to reposition speakers. Oh yeh, they add no sound. Have not found anything better. Of course, I am no longer looking!
I'm just say'in ✌️🖖

My new Super Stiff Springs are intended for *very heavy* objects, like Verier and VPI turntables and big amps but speakers like the 400 lb Magicas have such a high center of gravity it would necessitate a very large platform/plate under the speakers to be able to spread the springs out as wide as possible. Nevertheless the isolation, assuming it could be achieved mechanically, would be spectacular. The new Super Stiff Springs are low profile (2 inches tall) so they have excellent lateral stability. It would require about 8-10 SUPER STIFF SPRINGS to isolate a 400 lb. speaker. I estimate the platform would have to be 4x4 feet and could be say maple or Baltic birch plywood. It would be less challenging but interesting to isolate a large, heavy subwoofer using Super Stiff Springs.

My Legacy Signature III's weigh 140 lbs apiece. They sit on a raised wood foundation. They really came into their own when I put them on one of Mapleshade's 2" thick, unfinished maple platforms. The platforms are spiked to the floor though the carpet ... and the speakers are spiked to the platforms. It was very cost effective to do. If I remember correctly, the unfinished platforms were $175.00 ... and I already had all of the spikes on hand. I bought the unfinished platforms because of the cheap price. I wasn't sure they would work as I intended them to work. Now I wish I would have bought the finished platforms from Mapleshade. They're quite beautifully finished.
