Box and Tweeter recos for 4 Way Build: 2245J (Mid) + 2202H (Low Mid) + 2225H (Low).

Hi! Got these components and would want to build a horn based 4 way system with Minidsp and Dirac handling time alignment, eq, and crossover.

Intended use is for a low distortion, high efficiency home speaker.
Max of 80-85db usage range.

Plan to use a Yuichi Horn (but open to suggestions)

Planned xover usages:

2245J: 600hz to 6000hz
2202H: 200hz to 600hz
2225H: 20hz to 200hz

A few questions:

1. Can anybody recommend a JBL tweeter to partner with this design (hopefully of the same vintage). And the best way to implement it given the other parameters (top mount, mated to another horn, bullet???)

2. Any box plan recommendations? Max I can do for width is 18" and Max I can do for height including the horns is 42". Someone said to me to seal the 12" midbass inside the box and give all the free space inside to the 15" woofer to extended it's LF (dunno if Im making sense here haha)

3. Are there any better options rather than a yuichi horn given my xover goals?

4. Any xover slope recommendations (leaning towards 12db/oct BW)?

5. Were there any other JBL products manufactured that featured these 3 components 2245J / 2202H / 2225H?

Thank you in advance for the answers attached are the pics of the components.Name:  JBL Driver 1.jpg
