Thanks for the replies, the horns are machined in wood as it offers the best sound and the profiles are specific for drivers used. The other loudspeaker parts are run through saws and veneered but it may be an option to consider as the biggest panel is 1000 x 520mm.

Sturdy, precise, that's what I am after as it will mainly be used for machining the horns, I have had a brief look through the site here and EXEL seem well though after. I am a novice with regards to CNC so is the consensus that it is possible to make these horns leaving say a 240 grit sand and finish or am I asking too much. Any advice on particular machines they may recommend for this purpose?
