Hi all, I'm new here

I'm interested in your opinion on how you would built a speaker box(times 2) for these tree component :
-JBL 075 bullet tweeter
- Altec 511B Horn with no name compressor
- JBL 2241H woofer

Using an electronic 3 way crossover 2 x yamaha M-40 and 1 x M-35 for the tweeters

For good heavy sound, but don't need to work at maximum will play in a max space of 40 x 40 feet

Personaly I thought about a vented 7 to 11 cubic feet with possibilité to close vent, the woofer a good 6 to 10 inch from floor, horn over woofer and tweeter between the woofer and horn.

I'm wondering if it is a good idea to align all components diaphragm ?

Thanks in advance, cheers
