Sonus Faber Guarneri - will any aiddtional isolation be beneficial?

Which speakers do you have? As long as they fit between the raised pods on each corner it should work, overhang should not be an issue (as long as it’s not excessive). As far as tilt is concerned I would avoid using the podium to do that so as to provide as stable a platform as possible and avoid stress on the springs by having them at an angle. A very small tilt may be possible. You would be better off using the speaker feet to address the tilt.

The other option is to use the seismic bars or corners which are a) a little bit cheaper and b) would obviate the overhang problem. My instinct would be to go with the bars which I imagine you could level independently hence getting the tilt you want. Strikes me this may be tricky with the corners (with four seperate ones to level) but not having used them recommend you call a knowledgeable dealer for advice -- I used Analogue Seduction who were easy to work with

Hi Folkfreak,

Thanks for your response.

I have a pair of SAP J2001 speakers, although I have switched out its midrange horn in favor of very old Western Electric 731 b driver and a Western Electric KS 12025 horn.  The bass cabinet should barely fit between the feet of the largest Podium.  

As for the tilt issue, I would prefer not using any kind of feet on the speaker so that the platform of the Podium is in full contact with the bottom of the speaker.  That would allow for the best transmission of vibration generated by the speaker into the platform device for dissipation (this is what Symposium said about use of their platforms under speakers).  I could put the Svelte Shelf under the speaker and use either the Townsend Podium (with some sort of riser) or the Townsend Corners to support the shelves.  

Larryi -- not sure I'm confident that the Townshend stuff would match with the Symposium at all well. If I understand it correctly the intent of the Townshend podiums is to isolate the speaker from the floor and not to dissipate vibration in any way -- using multiple add on footers/platforms/springs may lead to them fighting one another which is why Townshend recommend you remove all feet when using their kit. Maybe if the Symposium platform is more an extension of the cabinet, then the podium/pods are the feet it makes sense? 

Denon 1, I think the G’s benefit from a couple of things. Like most speakers they are best when away from the back and side walls. As to isolating the marble bases, well i think that this may be desirable on a suspended floor, but not so much on a harder/non-suspended floor...or carpet. I have thought about adding an isolation base-- not under the stands, but between the stands and the speakers. This might prove to be beneficial....but it could also introduce problems. The biggest issue I would see would be that the speaker is now raised too high off the ground and the seating position therefore would typically be too low. Is there a reason why you are not happy with your current set-up?
