Round boxes are supposed to be better for standning waves and such but unless you are gonna compete it wont matter to much, so square or round is up to you..I would just keep it simple though. It is better to have two seperate enclosures for them instead of one big one..A divider is fine and fairly common.

Don't forget that the inner dimensions are the ones to calculate box sze with not the outer. Other than that it is pretty straight forward.
