I have a box that is 5 ft3 after sub displacement (2 subs one common chamber) and I want to tune the box to 35 can some one punch in the number and help me out. My box is only 13" deep so keep that in mind.

you didn't say, so I'm assuming that 1 woofer is going into that box. 1 4" round port 10" long will port to about 37hz or...35"^2 of port area 10" long will port to about 35.6hz
