| Re: Please help me understand tuning a port
It is correct that length and diameter as well as volume of the cabinet determine the tuning freq.
Below tuned freq. there is a possabilty of bottoming..could lead to damage...some use a subsonic filter to safeguard themselves
Changing the tuning you would change the volume or length of a port...the diamter needs to stay the same for the same driver...bigger driver = more air moved = bigger diameter port. If not you would experience port noise
Physically measure...use test tones...when the driver cone is not moving...meaning that the port doing all the work..that is the tuning freq.
Hope this helps....
