Isoacoustics don’t seem to work for me, help

Townshend Podiums. A lot better than Gaia anyway. My carpet isn't that thick but the pad is pretty thick. Another guy with Podiums and a thick carpet found they were even better with a butcher block under them. After hearing that I tried BDR Round Things under mine. They were excellent even before but sure enough that made them even better! Why something placed under a supposedly isolating spring makes such a difference I don't know, but it does. Just goes to show vibration control needs to be tailored to each individual application. 

Your speakers are not very massive, but they are tall and narrow. Not the greatest for stability under any circumstance. If you can afford Podiums that would probably be the way to go and I would contact John Hannant at Townshend to find out. They have used them under very similar small floor standers successfully he would know the trick if anyone would.

If Podiums are too much the bargain approach is Nobsound springs. You would have to make some brackets to put the speaker on that would extend out from the sides to improve stability, but this could be something as simple as MDF or even a 2x4 which if you do it right would not need to raise the speakers up at all. Watch the above video at about 3min in to get some idea how the brackets would work.

A second on the Townshend Audio Seismic Podium. If the cost takes away your breathe, buying individual Pods and using them under a good platform (perhaps one layer of Baltic Birch plywood, one of Slate, with constrained layer damping---such as Acoustic Science Corp’s Wall Damp---between them) will make for a more affordable solution.

You need something that spikes through the carpet if it wobbles its the wrong footer.Ask the company or sell them.

Look at Symposium speakers stands they have adjustable copper spikes the best sound.

Starsound speaker supports would be another choice for carpeted areas.

@ebm   Yup they are for sale..I tried again with the ISO spike cups no good. 

+1 on the Star Sound. I have the  Rhythm’s and they are freakin awesome...

Im sure it is not Symposium stands your talking about something else not Symposium Acoustics based in NJ .

If you're going to be in this room for an extended length of time, removing the carpeting is an option, if an extreme one. ;-)

Put the original ProAc / Track spikes back and I’m happy. At least I can recoup most of my $$ and put that towards my Hugo TT2 fund.

You mentioned speaker height so this may not be a contender. Concrete paving slabs. Painted black. Then add the springs etc.

What made a night and day improvement for my speakers are Stillpoints. If you speakers have screw holes on the bottom you can get Stillpoints that screw in. The work well on carpets or hardwood.
My speakers are almost 200 lbs and I got away using the least expensive Ultra Minis. Really, the improvement was like I doubled the perceived value of the speakers.

OP you need to get the carpet spikes. 

My Gaia Titan’s sound better on carpet without the carpet spikes. 

Another vote for the Townshend podiums. They work really well.
