Forget about the HR4020A, they won't do midbass and there is a terrible mismatch between their pattern and the 9040.
The EVM 15l won't be a sub no matter what you put it in. It's a mid bass woofer.
Frankly, I doubt the ST350 has any better highs than the 291. There are much better tweeters.
Something else for a sub, the 15l for mid-bass and the 291 for HF is a good place to start. Try the ST350 and see if you like them.

I'd recommend active crossovers.

Thank you for the advice and will look into it

Thank you for the suggestion and will check it out
