squared port but im gonna get some pvc or any platic tube big enough to use to round the inside corner of the port so that the port remains the same size all the way through. if you look at the picture of the inside of the box you will see in the port that the corner is rounded.
not going for spl more for daily but a decent score with a daily setup would be nice.
