box design?

[dirtboi22]

ok, so my previous box held two 15's and it was just one big chamber with a slot port. but im building a bigger box now a was interested if two seperate chambers would be any louder than one big one. idk if this will affect any way but im using 4 pvc pipes as ports.

usually 2 separate chambers theoretically helps with control/box rise/reinforcement, and it gives you the ability to play the good woofer if you blow one up

its usually a good idea if for nothing else than that baffle between the 2 chambers reinforces EVERYTHING
