Karlson K12 PA Project

[Paul J]

This is my first speaker project. I started with 50 year old karlson k12 enclosures that my father built. My design goal is a 2 way, full range, bi amped system. I built new horn enclosures and refurbished the karlsons to match.
The horn lens is Dayton H812 and Selenium d220ti-8 drivers.
I'm looking for recomendations on a 12" pro audio driver that will work well with this combination. Eminence beta 12a? Selenium 12pw5?
In particular with the karlson design.

LF amp Samson S1000 360w/ch @ 8ohms
HF amp QSC mx700 150w/ch @ 8ohms
Active crossover Behringer cx2310
Processor Behringer deq 2496

My question is - am i on the right track?

The Karlson enclosure can be modeled as a series tuned 6th order bandpass box. Doing so is the only way to predict the best driver choice for it.
