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

My Transmission Line's sit directly on the floor, they dont accept or have spikes.

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!)
