Would there be any noticeable difference between making one huge box or leaving both of them in separate boxes, advantages? disadvantages?

There would be no real benefit to having 2 boxes as opposed to 1. It could make it easier if you had to haul some stuff around and just need to free up a little bit of room, then you could just slide one box out. If that's not an issue, just make 1 box. If anything I would imagine 1 big box would play better, due to both subs having the exact same enclosure, but it shouldn't be audible if not.

i didnt think so. do you know if the new BL line will be any different from the older line?
