I saw a picture of what think was a prototype on AVS, is this a coming kit? it would be perfect for something I am planning Big
I think you're talking about the prototype L/C/R Erich posted a pic of over at avsforum. If so, that design isn't complete and he's still working on it.
Here is a similar design ... used a BMS 4550 and a SEOS 12 instead of the 15 http://www.diysoundgroup.com/forum/index.php?topic=228.0
if you don't want to wade through all the post, Erich said it will probably be ready in about a month.
