help hds215 box design

[rayfrausto]

Hi guys this is my first post here, ive lurked these forums for a while reading and learning. I'm planning on building a system from ground up. But for now I'm gonna fork out a little cash to have some slump in the meantime. I'm going to order 2 sq hds215's. And was wondering if anyone can design me a box for them. (JOE X designs are great ive actually build one he posted for 2 cvr and it woke them up hopefully he can chime in). Specs/info below
