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

Car stereo .com is where I found that port calculator Phemps... Check it out. Takes into account diameter, x max and tuning. Calculations based on Thiele and Small formula for port size... Seems legit to me.

Hey buddy;

I am on the same boat as you. I have 2x tc sound lms ultra 5400. They are going to be powered by 2x Audison lrx 1.2k. I have a space available for a box of 48W X 22H X 28D. I need to figure out the same as you..
