The port needs to be port width away from the back wall...at the least.

each port should only be two inches wide after it splits.

What program was used in making those design images? I've been looking for a program to do something like that to bring with me when I go to the woodshop for the final build.

I just meant if he wasn't going to have it split into two different ports. But I guess since the port's in the middle you can go half the width from the back since you'll be getting air flowing into the port from each side of the port. I'm used to doing potrs on the side so I've gotten a little rusty when it comes to splitting/center ports.

I'd make the port a little skinnier (down to 3.75) so the port's longer to lower chances of port noise.

yea with it in the middle it splits into two separate ports which have to combine to make the main port opening

wasn't callin you a tard or anything I'm sure you know you're stuff just a mistake ;)
