I just had someone tell me something and I need to verify with you guys before I change anything.

If I have 4 of the exact same sub, and they are all in sealed (seperate) boxes, would I actually get more out of them in a shared airspace box?

Mine are set up so that I could easily accomplish this just by swiss cheesing the dividers

its hard to know for sure because when you have multiple subs sharing the same airspace they will interact with each other. usually this makes the sound quality worse overall but if all you care about is loudness then you might gain something, might, its also just as likely that you could lose DB.
