Hi:
I have, and plan to use 8 Altec 806´s with non OEM phenolic diaphragms, (China, cheap) with JBL 2345´s, for voice paging in a big lot, about 55,000 sq ft; I will try stacking, splaying, etc; The question is: Will it help if I put a 10" long tube between the driver and horn, to prevent the diaphragm from unloading?.
I plan to use caps and resistors to avoid any thump or LF from the amp.
Thanks.
