I have only done one box with rectangle ports but the sound quality i think i not as good as a regular port. The rectangle port bounces the sound around to much a give it the kinda dull sound. Now i admit they do look pimp but for a loss in sound quality in wouldnt use a rectangular port.

Ketel22 is correct it should be 3"x10"x15, which would give you a port area of 30 sq in. You could also go 2"x15"x15 Is this a MMATS pro 15? https://www.mmatsproaudio.com/pdfs/recommendenclosures.pdf

You would probally get the best all around sound and looks by making four rectangular ports so youll have enough air for the 15. -------------

yes it is the pro 15 and what is the advantage of have the port turn at the end instead of have it just go straight down
