JohnThe spec sheet I have for the BM-15CX38 lists Fs at 42.9 Hz and Qes at 0.322. The Fs/Qes (aka Gross Bandwidth Product/GBP) comes out to 133 Hz, still a candidate for your application which is a hybrid direct radiator and back loaded horn. Dr. Edgar's comments in the Positive Feedback interview were in the context of specifying a driver for a bass horn (which would need to be able to get up to 400 Hz or so, to integrate with a compression mid horn) which his Show Horn and Monolith designs were. I'll send you a sketch illustrating the angled corners for the Olson design adapted for a 15" driver (50" tall, on paper at least ; )
