Thanks so much for the ongoing coaching, Peter.
I see how the newer TT-22a's lower HF crossover frequency improved directivity....like in your DIYs....
Which is one reason I've been keeping close to crossover at around 650Hz crossover as in your boxes..trying to take advantage of the horn directivity as far down as possible.
Yes, I'm kinda expecting to probably run out of HF when arraying 2-3, at least down to where the horns are holding directivity.
And I am a little concerned with overdriving the HF, particularly given the crossover type I'm using.
I've been wanting to ask you, given the steep knee HP I'm using, what you think the safe freq should be for the 4594.
I realize the steep knee puts more loading on the driver. Does 7000Hz still work for more power, or higher?
The steep knee is pictured below vs a LR 24.
I'm using such a steep xover to minimize the freq summation range between mid and HF, figuring that helps minimize off-axis variations.
It seems to help alot, especially since my box doesn't enjoy the much better acoustical focus of the PM 90/60's with their dipole mids surrounding the horn.

As always, please feel free to tell me where I'm screwing up !!
