Post Subject: Any hornPosted by dragan on: 1/8/2012

Romy, I use MDF primarily, plywood occasionally and solid wood if I am forced to.
Round horns are precision CNC made within +/- 50 microns.
However, during sanding and finishing process the accuracy is somewhat spoiled.
The final accuracy is +0.05 / -0.5 mm, for smaller horns even better.
Rectangular bass horns are somewhere between +1/-1 mm.
I believe that, I have never actually measured the accuracy :-)

I am opening a new cabinetry division abroad. I don't know if I am going to be able to produce any of the loudspeakers in the next couple of months, but i am willing to talk about it, very much.
