Hi Tim!
Nice project you have going there!
May I ask what amplifiers You are using?
I also wonder how You mounted your drivers to the horns. I've been trying to find UNC 1/4" machinescrews with countersunk heads, but it's impossible. I've searched the net for any info regarding retailers that ship internationally, but for no good...
Regards: Jakob (who also will get a pair of horns from Mats! )
