Just ran the design through Hornresp to see what they actually could do with the power we had back then, it ran out of Xmax at about 245 watts per cone, which is about what the Crest 8001 amps could deliver.

The L4 tuning (about 45Hz) was lower than your box, but they kicked like crazy considering the low power and short Xmax (6.4mm) of the speakers used. We had 28 L4 cabinets, though the most we used at once was 20.

Be sure to use a HP just below your box tuning, or the speakers may develop some holes if you play anything loud and low .
i recommend my friends build and test for diy people whe have less money. some pics i get them from the diy feed back. most of difficult is the short xmax because the cheap drivers, yes hp helps a lot. all the drivers drive 200 w will be ok. my plan likes the d&b c4 but after i simed the d&b c4 i was not satisfy. because i wanted to hit the db. the design isn't too low because its easy to make the problem with the excursion. many und many diys are satisfy the tha f horn v.1 i see ur plan seems like 2 drv in one box. like the eaw with v shape , it looks ok u have the good work as the same.
