Don't Jim's loudspeakers already come with cones? 
(My apololgies for butting in; I know this wasn't directed at me).
Yes, they do. And very nice ones.
In my case I did not go with the standard feet that come with the HT2-TL. I went with the bullet shaped feet that normally come with the SoundScape 10/12. I like the look better and am not looking to replace them; just to put something under the feet to make it easy to move them.
I already have some larger furniture glides that work well, but they are too big (4.75" wide) and butt ugly.
Perhaps I'll try the cheap ones first and if they don't work out perhaps splurge and try the Herbies.
BTW, I'm not looking for any sonic improvements, just added convenience.
Keep the great suggestions coming.
