A buddy of mine built a box for a friend of ours using winisd. But as I was looking a it it clearly didn't have enough port area. When I put the box specs in to bass box pro it had 26 m/s of vent air velocity I redesigned a box 1 cube bigger with almost twice as much port area and my vent air velocity is 13. My output chart also shows to to be a bit louder at the lower levels. What is optimal for port vent air velocity in m/s? also Is it bad to have turns in slot ports ?
