I can supply CAD files, but he'll have to set the depth for the flush routering, etc.
Also, you guys know that I charge the retail price of all the parts, there's no upcharge for my R&D and the crossovers come assembled on Mundorf Matrix boards with quick connects, so no soldering in required as long as you have some good crimping pliers!
Regarding cost savings:
I've got a more cost effective RS Series version of the Dynamic Series finished and online now. There's a significant cost savings using the RS line of drivers. The pricing on my site includes everything you need to build the speakers, so while it might look a bit more expensive at first, don't forget that everything you need minus the wood is included in the price and a lot of the BOMs posted online for other speakers do not include these items.
FREE shipping for anyone that gets the flat pack.
