A 2447 don't sound so spectacular above 8KHz, so I'll need something to finish off the top cleanly to beyond 20KHz. I have everything except the very top already. The bottom end is another question altogether for me too. I have some JBL cabs with dual 15" 2035's from a movie theatre, made out of particle board, which would easily be destroyed using them for PA gigs.
Lately I've been thinking of trying out a BMS 4"+ring radiator coaxial compression driver on the big JBL2352 horn. Rumor has it that the new JBL ring radiators are BMS designs that JBL licenses to build here, and that's a good sounding UHF driver. The 2352 holds its Vertical and Horizontal pattern control extremely well down to below 1KHz, and fully loads the driver down to below 630Hz. I may even be able to run a pair of 15" or the right 18" up to meet the horn and end up with a three-way system, which would simplify design and tweaking considerably.
