Have you talked to Daniel? I thought they were laid up by hand, no?

Thanks for the reply.

No, I haven`t spoken to Daniel; actually I don`t know who he is.

I heard that there were plans made up for CNC Spiral cornus - maybe I am mistaken...?

Not that I know of. He used to have his own forum but I can't seem to find it now.

I would be really interested in helping to develop this idea. There is currently a member on DIY audio who is offering CNC milling at great rates: http://www.diyaudio.com/forums/showt...hreadid=131337
Perhaps we might even get a group buy together of the front and back baffles and then glue the inner ourselves from some ripped 1/8" ply

Here is the link to a Cornu build which offers dimensions:

I cant vouch for the dimensions so it might be worth contacting the builder

I think that's Sebastian's version, not an actual Cornu design, no?
