In the case of tuning a ported subwoofer box there are two ways to do it.
Pipe inner diameter unit of measure inch this is the inner diameter of each tuning port.
If your subwoofer is in a ported enclosure you d set the hp control to 10 hz above the enclosure s tuned frequency.
One of the key ways to control cone movement below tuning frequency is to use a subsonic or infrasonic filter just like we recommend for infinite baffle.
