Posted on i have a piece of PVC 4" pipe and a 90degree elbow....i have to use this to make a port in an L shape...
i used a calculator on a site and it said that to tune to port to 34hz i need to make my 4" port 21.55 in long....
so do i measure the port in the inside of the curve of the outside??? |

Posted on I know with a straight slotted port, the effective port length is measured right down the middle, i think it would be the same for a curved port. |

Posted on Probably outside plus inside divided by two, which would be down the middle. |
