Hello,
I'd like to play around with a Jecklin Disk between my Earthworks TC30ks for stereo recording, so I thought I might try to build one, instead of buying one, since I just want to try it out. From what I can tell, the basic requirements are the it's wood covered by foam, round, and about a foot in diameter. Anything else I should take in account? Or does it sound so bad I shouldn't even bother

? Does anyone actually sell them? I can't find anyone who makes them.
Thanks!
