I everything goes well, I'll be cutting for my dual driver VBSS this weekend. I'll be aiming for a 20Hz tune, which Matt said would need a slot port of 18" deep by 2.5" high. One caveat I have though, is I am turning the box where the 28" side is the front, so I only have 20" depth. Is it safe to assume that if I put an elbow on the port and leave 2.5" the entire way that I will be good on tuning?
