[QUOTE="Peter Morris, post: 208472, member: 652"] The original idea was to build something like Meyer's Leopard but rotate horn 90 degrees and then stand the box up. I found that if put each of the 14" drivers in their own chamber I got better results. I also needed to reduce the size of the LF drivers exit slots to control directivity better. The problem with this design is the HF horn, its a wonderful horn (90 x 40 pattern) but not available for purchase. A bit of info about it ...
