Townshend Audio Podiums - current owners opinion on the merits of this product

@garebear  I have a pair of Townshend's Seismic Isolation Podiums.

I'm not sure how to interpret your sentence / request:

I ... would like to hear from current owners or members who looked at them and didn't buy or have sold them.

Can you clarify? 

@garebear   Got it. Thanks.

In my case (due to my speakers) the application of and results from the Podiums is more complicated / difficult to transpose to what I'd expect from 'standard' speakers.

I believe this also applies to your speakers:

That ‘plinth’ it rests on is in fact a high-mass chamber for a down-firing, isobaric-loaded pair of 170mm Tactic drive units (WB’s own design).

Since the base of your speakers is of a 'specialized' design and they are down-firing, I recommend reaching out to Townshend and Wilson Benesch for guidance. 

Both companies are England based so there are bound to be local owners of the Square 5's that are using Townshend Podiums.
