The Townshend Seismic isloators are also available separately, as individual "Pods". Using three or four of them under a speaker (or any other component) provides isolation to a very low frequency, and is cheaper than the Seismic Shelves themselves, which are not really required---the Pods are doing all the isolating, not the shelf.
Sorbathane under granite slabs for speaker bases?
I’m getting two 12"x12" granite slabs to use as bases under my KEF Reference Model 2s via spikes. They will be sitting on a 5" high hollow tile shelf. Would using thin (.25") 70 duro sorbathane under the slabs help in isolating the speakers or will it possibly negatively impact the sound?
Thanks for any input.

I should have mentioned that the Townshend Seismic Isolators are also offered on a number of different "platforms". In addition to the individual Pod which can be used in sets of three or four for use directly under a component, Townshend makes the Seismic Platform, which is a thin shelf with a Pod bolted onto each corner, onto which a component may be placed. There is the Seismic Podium, which is similar but for a speaker enclosure to be placed upon. Then there is the Seismic Bar, a pair of outriggers for a single speaker with a Pod bolted onto each end. That is good for the narrow/deep proportioned speaker enclosures, the outriggers giving the enclosure a wider, more stable footprint. Also available is the Seismic Corner, which has a pair of Seismic Pods bolted onto a metal bar that is placed under the corner of an equipment rack, four Seismic Corners obviously required (with a total of eight Pods). And then the Seismic Rack, which has a pair of Pods under each corner of a four-shelf rack, each shelf being a Seismic Platform. Each individual pod comes in seven weight-appropriate versions, from 2lbs. to 140 lbs. |
ebm For the best sound look at Symposium Super Plus with spikes for cement floors or without for all wood floors, Granite rings and is tipped up for thin highs,Good luck though. If you’re afraid that granite rings when you strike it, don’t strike it. When granite is placed on springs it’s isolated so don’t worry, everything will be OK. |
asahitoro - sorbothane is a tricky material to use. One might think more is better, but my own experience leads me to believe less provides greater benefit. I use it throughout my system between the feet and the components. As an example - My turntable was sounding great with 1/10" sorbothane on the feet, so I thought I'd try two pieces of 1/8". The result was terrible - the dynamics dropped off and the bass became bloated. I'd opt for 1/10" sorbothane in your case and even then - I'd put a small 2x2 inch piece at the corners and one piece in the middle I also spoke to an HVAC installer that uses it to curb vibrations and he said using strategically placed smaller pieces is often more effective.
