Hi Nick,
Do you have a 3D printer? If you do you can create much more optimal ports to reduce turbulence. Or just to optimise port area by creating ports shaped like this:
But always remember guys! 4 separate subs are a lot better for clean bass than 1 big sub. Great bass management video from audioholics here if interested. https://youtu.be/5IdclF3MZ8I I put the link for pt3 because this is the one that talks about putting in positions of 4 subs. Just thought to put this here in case people think of splashing their money on just 1 subwoofer 😉
