making a box tomorrow for a guy with 2 type r 12s. i drew it out to 5 cubes net tuned to 35 hz.. its got 94" of square port area, and a 7 inch port opening.. is this going to be too big? should i size the box itself down a little, and is that port mouth too big?
I'm not sure if this translates but one of the guys on here recommended 60 square inches of port for 4 Type R 10s, so I'm guessing 90 might be a little big for the 2 12's
