Re: I have an opportunity to sell my box!!
Your port is way too small, I did that too on my first box.
The problem is, you should keep the width to height ratio of the port less than 9:1, so you port should be at least 2 inches wide, preferably 3 actually.
And you port area in sq inches is not enough. You should keep it around 14-18 Square inches of port area per cubic foot. Right now you are sitting about 4.5 per foot.
Torre's Calculator is great because it let's you add in all displacements and gives you the accurate Port area per Cubic foot measurement.
