    How much port area does my TC Sounds LMS 5400 Ultra 18" need

    I just got my TC sounds ultra 18". I am going to put it in a 3.4ft3 box tuned @33hz. I was wondering... would a port that is 3" x 17" be big enough for this sub and box?

    I can go a little bigger if necessary. I can go 3.5" x 17" on the port. If anyone is not familiar with this sub it goes in small ported or sealed enclosures. Heres the links for the sub:

    According to the port area calculator on Car audio, tuned at 25 HZ you will need 126 square inches of port area. It will be more with higher tuning. Sounds super high I know. The calculator takes into account the subs diameter and its X max.

    So you're telling me I need a port that is 8" x 17"? That sounds ridiculous for a single sub.
