DIY speakers

Not really sure where to post this so taking a shot here. I've research a few highly regarded DIY speakers that would contend with high cost retail speakers. 

I've decided I want to go down that path and wanted to see if other members have thought the same. 

A speaker model I'm interested in is http://www.troelsgravesen.dk/CNO-4.htm

You purchase the drivers and the kit with everything you need including schematics and cabinet construction info. You get top rated drivers, respectable xover parts, and the option to use whatever material you would like for the cabinet. 

The cabinet building is more for the wood worker who has the time, skill set, and tools to build the cabinets. I possess two of these necessities. 

I would prefer to do a CAD model and program a large router with set up time and cut all the panels, driver cutouts, port holes, bracing, etc.... at once saving me the time I do not have cut the cabinets with saw. 

The cost per unit is reduced if multiple pairs are being made at one time so only one set up cost. 

I'm reaching out to members who would be interested in the above speaker of on that same website the Atell 3 and Purifi-6661.

The three models I've listed I'm confident would reach in the 20-25k retail category easily with the quality of the components. 

If any members are interested please state and which model.
