Ok, I know to never position a port directly behind a driver, but other than that does it really matter? I'm about to cut the face of the cab (speaker baffles and port holes), but I only have room for the 6" ports on the bottom right and top left. Will this pose a problem? It's very much like the aguilar GS 412, EXCEPT, instead of having a tweeter at the top I'd had my second port. So yeah.. very bottom. very top.
