It's funny, I have 4 of these, and I'm thinking of finally doing something with them, after my recent project. I googled it, then found this post, then I found my old Madisound lit. (may 97) Now I've joined the club here. After figuring out the Audax equivalent, I found it in Leap.

Here is the Madisound page.

Here are the Leap specs, that someone uploaded to Linerx:

* End

This is a very impressive bunch of drivers. In terms of response, they do better than the Aerojels. Has anyone heard them yet?
