Well I guess you could try?
I don't think you may find that many Klipsch fans here, but I know there is a Klipsch forum that would probably be filled with people interested in your cabs. The originals were nothing more than just veneered boxes. ( I guess that can be said of all speakers) but some guys go beyond the veneered box approach, Salk for instance, his boxes are gorgeous.
I know a couple horn guys, and these guys seem to have a lot of experience in audio and tend to be the DIY type.
Good Luck and Welcome to Audio Circle,it's nice and warm in here!
