You?re welcome!
OK, if the size of his is fine and doesn?t make the horn height too high, then just build it with the driver down 9? o.d. from the top same as the M19. Note that there will be no opening to acoustically couple the horn cab to the bass bin, so there must be some serious damping in the spacer cavity to keep it from ?drumming?, so consider filling the void with scrap knot, void, free wood, drywall or similar. This also helps to mass load the [ML]TL to the floor.
The cab is large enough to have considerable latitude spec wise and cover pretty much all the different 416 specs with enough room to spare to allow/need some form of EQ to flatten it out in room. With rare exception, all the cabs I?ve used/designed are technically too big based on T/S specs.
I currently don?t have access to the sim or my write-up, but just from what I found on his build thread you can add up to 6 ohms of series resistance before the cab starts getting acoustically small based on GPA specs, so plenty of tuning flexibility.
