So just pretend my port section is a box and tune against that volume? thanks for any help in advance..this is my first 4th order hoping that with the easy changing port it will do good.
I'm going to be starting my first bp pretty soon also but yea supposed to tune according to the ported section. There can be some other factors as well.
