Find Tuning Frequency for Odd Shaped Ports?


Recommended Posts

I was playing around with a box design that has 2 triangular ports,if i done it correctly i figured the port volume to be .13 for each port.

But i have no idea on how to figure out the tuning frequency,is there a formula that you can use to determine this.

Here is the box that i was playing with,and so you don't get confused the actual port length will be 17-1/4".

Trying to learn something different.

well for one, 2 triangle ports will just equal 1 square port....

just take that sq in value for your port and see what length you need. it is that simple.
