Interesting and review in HiFi +. Goes against the "traditional" spiking speakers to the floor method.

For subs, I use Auralex Subdude, that I bought second hand and can be built rather easily on your own.
The Townshend is way too expensive for my blood.
And there is always Herbie's stuff for speaker isolation...
Thanks for the link
Best,
Anand.

I don't believe the graph showing the vibration isolation performance of sorbothane dropping to nothing by 75 Hz. That's very misleading, I would say.
Properly chosen sorbothane hemispheres of the right density and size can be extremely effective down to the same frequency range as shown for the Townsend product, and for vastly less money. The only advantage to the Townsend device is the increased stability allowed by the widely spaced feet and perhaps better looks. apparently there are better absorbers than Sorbothane, too, although they are more expensive.
See this thread for lots of detailed information:
