Isolating Transmission Line speakers from floor


Gday, I have a set of Australian made Transmission Line speakers(as pictured) I live in a rental with floorboards, looking for a way to isolate them. Can anyone offer any suggestions?
May also be needed for another rental in the future, which may have a concrete slab....
Cheers Andrew

Spikes will definitely increase coupling. Townshends or feet like Isoacoustics Gaia will decouple.

I use Isoacoustics Gaia feet with mine and swear by them.
I used Gaia's on a set of Tannoy XT8F's, great result. Even the "Minister of Finance" was impressed... 
Well then you will love Podiums, a couple guys had Gaia and said the Podiums are a lot better. (Should be for the money! lol!)
