Coral Flat 10 schmacks horn

[skvuppla]

I have a pair of coral flat 10 and I've been thinking of building a pair of shmacks horn with them, but how do I know how to dimension the horns?
I've also been thinking of adding a super tweeter or maybe a regular tweeter would be better?

I'm also interested in getting a sinovt amplifier to drive them but wich one would fit best? sinovt amplifier

regards

anders

You have two variants of the Schmacks horn in a zip file at Isophon-Archiv Bauvorschlge
The Schmacks2 is the version updated by Isophon with a smother horn path than the older version😉

I've seen some that are bottom ported (on legs) and they look much nicer than the front ported ones. But i've never come across any drawings..
