Coax / tapped horn speaker

Howdy. Wondering if anyone has considered a 4-driver PM90 with some of the new B&C coax drivers? I was thinking one could probably achieve a high-SPL box that's still pole-mounted. I was looking at B&C 8NDL64 drivers, which are less than 6lbs each. Add that to the B&C DCX-464 and either their ME464 horn or the RCF HF950 and you'd have a Loud full-range speaker.

I've been looking at the Meyer X40, Peter's PM90, and the Danley SM100B. Danley uses four less powerful drivers to keep up with the 5" coax mid/high. Peter has two horn-loaded drivers. Meyer just has two angled front-loaded drivers with a slotted port on the X40 and two slots on their larger X80.

I was thinking that Peter's design with the B&C horn would leave room for a pair of 8" drivers at top and bottom. Total component weight plus the horn comes out to less than 45lbs with crossover.

Thoughts? Anyone wanna throw this into some software and take a look? I'm an ideas guy - no idea how to run hornresp or any of the other fun toys.
