I acquired a pair of L100t speakers a while ago in rather beat up cabinets. Having always liked the C34 cabinets, I decided to build a pair as a new home for the components.
The C34 enclosure is roughly the same size as the L100t, just a little lower to the ground.. About 3 cubic feet, tuned to 38hz.
The cabinets are made from ¾ mdf with a fair amount of internal bracing.
For the feet, I went with these:

They are close in style to the originals and I am happy with the build quality. They are solid aluminum and roughly the same height as the originals. I think if you really wanted to duplicate the originals, you could have the feet turned down to the original profile at a machine shop, and still save money with starting from scratch. Anyway, I like them fine the way they came.
Just like the L100t, they sound great.
Here are a few pictures of the finished results.
