Jim Griffith minimonitor

Can someone please tell me the correct dimensions of the port in Jim's vented design for the Jordan/Aurum monitor. Thanks

Bern,

Well, I don't know about the Jim Griffith minimonitor design--did not know that he had one--but the Jim Griffin minimonitor uses a 1.375" inside diameter by 4.5" long port tube. It is Parts Express #260-388. Use it without the outer sliding or adjustable portion of the tube.

Thanks Jim and sorry about the mix up with your name.
Can you give me any tips on how to judge how much fill material to use? I have lined the interior with a felt material.

Thanks again
Bern

Bern,

My recommendation on stuffing or lining the box is similar to Brian's photo. For mine I used the 1.5" convoluted or egg crate foam on the back wall and then I wrapped the sides, top and bottom walls with 3/4" thick acoustic foam. Be sure to have complete air flow between the driver and the port.
