Looks real nice, another good build!

A question for you...

I looked at the template you used to build and tried to model it in winISD.

Using a 6.35 ft^3 volume with a 1"X21"X19" port shows a air velocity of 30+ m/s

Do you hear any chuffing in the port when using the sub?

It is quite possible I am simply modeling it wrong, but I wanted to see what you heard before I move forward with a build similar to this


Thanks !

Keep in perspective, many commercial subs when modeled would show port velocities up around 40-50m/s. I generally recommend keeping it below 25 m/s just to have some safety margin.
