Their compression drivers are even more "reasonably" priced but sound absolutely beutiful.


Where are you getting the 53g from?
The thielesmall.com doesn't seem to list a mms or mmd

If you're gonna play with an MT102 sized cab the aj-horn demo is fairly useful, as it seems to be restricted to a 0.5m horn length, which is pretty much spot on for that cab (PS. model half the cab....) The optimum rear chamber volumes from horn-resp & aj-horn seem to tie in pretty accurately for me, good software all around.

cheers,
Rob

This is meaner.

Anyone fancy an 11 meter horn with a Void V18 driver in it.

I'm trying the free demo version off their site It's got a few restrictions in it
Now a 30meter horn is something! Makes me think of the plywood tunnel used in the first h-bomb test, 9000ft long with a h-bomb as the driver Alot of noise for a short time....


cheers,
Rob
