Isolating Transmission Line speakers from floor

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!)

Unfortunately the only way to post images is on your system page. https://systems.audiogon.com/systems/8367  You are right, Townshend Podiums only raise the speaker very little, less than some spikes even. Mine are for Moabs, about 150lbs, they can make them for just about any size/weight.   https://www.audiogon.com/listings/lisa8e18-townshend-audio-seismic-isolation-podiums-size-4-570mm-43...

Being on springs the load should be balanced, which for most speakers the drivers being on the front brings the center of gravity forward, which you balance by having the speakers a little further towards the back. Your transmission line may have enough baffles inside that this is less of a shift. Not a big deal, they can also be adjusted level, just something to keep in mind.  

John Hannant helped me with mine, gave him the speaker weight and measurements, the result you can see, looks like they were made for em. 

Townshend Podiums are the high sound quality solution. Expensive, but worth it. But you want an inexpensive solution, Nobsound springs. $30 per set of 4. Springs are highly effective. The bass sound will still be in the room, but the majority of mechanically transmitted sound will be way down in level. Also if you go with Podiums they will clean up your bass so much it will be hard to believe.  

Either way, Nobsound or Podiums, they will work as beautifully on concrete as wood.
