Is this a factor of the woofer size or box size, both or some other variable?
My woofer is a JBL 2206 - 12" and the cab size is about 1/3 larger than a Model 4312 Control Monitor factory cab (e.g., a factory Altec Santana 2 cab) .
I was thinking of using a 3" diameter port which is similar to the 4312 cab.
Does the length of the port tube impact cab tuning?
Thanks...
