Wayne, the coils are backordered at Parts Express until 5/28 anyway. I'm hoping that since the 8pi kits are available, you have them in stock now and can give me a quote? Also, will I need the extra gaskets for the Alpha 10 in the 8pi, or are they just advisable for the Delta and JBL drivers in the midhorn application? I think this is all I'll need to complete the speakers - hope to have the cabinets finished this weekend and start on something for the horns. I'm thinking of the VOTT arrangement where the horns are left out in the open on top the cabinet and wondering how much support is needed for the H290's. Has anyone just fabricated some kind of bracket/stand for the 290's? If this were done, could the flange at the front of the horn be cut off, for appearance's sake? Just thinking.
