I am mid way through the tech renovation of a auditorium on a college campus, and I was evaluating the sound reinforcement. Up in the cat walk there are two Klipsch la scala k447 speakers that are pointed down towards the audience, my question is this. The horns are blown in both of the speakers, is it worth buying new k-77's or replacing the diaphgram, or are these speakers worth anything. They are painted flat black, and made out of 3/4" plywood. The one thing that puzzles me is that the woofer wedge is the opposite direction from all the other lascalas that I have ever seen. With the speaker sitting on the floor the Wedge is horizontal all the others I have seen are verticle. Also the box is only closed around the woofer the top and sides by the squaker and the horn are all open. the magnets and the crossover are all visible. It looks homemade other than the fact that it has all the original badging, and paperwork glued to the box. What do I have?
