Survey on Cost of Loudspeakers Supported On Townshend Seismic Isolation Podiums

I am aware that there are people here who use Townshend Seismic Isolation Podiums below the speakers. I am interested to know the cost (RRP) of the speakers which are supported by the Podiums. I’m not sure if my speakers deserve the Podiums but they are in my wish list should I decide to upgrade something in my system in the near future.

Any input would be appreciated.
