Seeking advice on a 4-way speaker project

Hi there!

I have been looking into building a project with the following drivers:

Fostex T900A
TAD 2001
TAD 4001
TAD 1601A

I wanted to see if anyone has done a similar project and has some tips on horns for the compression drivers, cabinet specs, and crossover. I would run these through Accuphase A200 monoblocks.

Thank you in advance!

Those are mostly similar, you need just one. Make the choice for the treble path. But the choices are dictated by the application, which can be particular and might require three tweeters, IDK !? Is the air particularly dense and humid ? 😏

For the drivers ( speakers, domes ) again, IDK! For me a 10" is classified as a subwoofer, I mean, usually I stop at 6-7".
