    3.5 cubes is pretty big for one L7... I wouldn't recomend going that big...

    2.5 per sub @ 35hz is good. use the availible space to make the port as big as possible... you want a HUGE port.

    i'm told that putting the port against one of the walls is best for SPL, but i opted to port mine in the center.

    if your port has corners, use PVC pipe cut into forths to round them off... you can also do this with all of the boxes corners.

    use caulk to ensure the box is airtight.

    if you don't slot port the box in the center, brace it somewhere in the midpoint between the port and the far wall.

    flared ports are your friend... if you're got a router, round over the openings of your slot port.

    and umm... thats about it.
