Main problem with both facing up is there is no reflecting wall.
we did a box a while back for 4 15s. The guy wanted a solid shelf over the box so we laid a board over the top at like a 15° angle and basically created a 6th order bandpass but in simpler terms we added a loading wall before redesigning the box
