would this be a "ported" box? I'm going to build one once i grasp the idea of how to make one. Anyone got a good webpage or something? I want to understand the box im making, not just use measurements, u know....

The port is just an opening on the top of you box to let air out (can be square, slot, or round) that is a certain width/length and goes into the box a certain depth (these dimensions and those of the box create the tuning frequency)

alright, i deleted that picture cause i found some stuff about porting. What will tell my how to calculate the port? (L-W-H) I'm going for a 5.5 cu ft, tuned @ 36 (FYI)

I have no idea what the actual formula is for determining port length. I've seen plenty of sites that have a port calculator, and they all have different formulas and some of them give out real wacky answers. I'd say email Steve at ED and see what he can come up with
