djlivex asked for a simulation with Faital Pro 15FH500

It is very close to JBL 2226 (compared in graph):

I also did a simulation of 4 cabs in half space using Faital Pro 15FH500 powered by 1,3 kW:

Thanks quinnling!

Should I assume that this design will work just as well for the JBL 2226J (16 ohm version). What is the dimension of the horn.

I cannot think of any reason 2226J would not work.

The dimesions are (HxDxW) 1196 x 936 x 494. Millimeters, you better get used to them :). It is build with 18 mm Russian pine plywood. Next cab will be Swedish birch. You will need 2½ sheets of 1220x2440 plywood for one cab.
 
Actually I built a tapped horn for 2226. Not bad, but this one sounds better. The tapped horn sounds like a bass reflex on steroids. This one is cleaner and with much more energy in transients. It needs a big room.

This one is 50% bigger than the tapped horn. I can get as much spl from this horn as from the tapped horn, both tuned to 30 Hz.

This horn has a much better group delay than a tapped horn. It will behave very nicely outside of the crossover passband. You will need a digital delay in order to avoid comb filtering and to get full attack in transients.
