thank god somebody responded - I wasnt to sure i was in about the same area between 28-29hz really didnt sound right to me. What is everyone using to calculate this figure - computer program?

I got a quick question is the CS Area port width x port length or port width x port height?

^^^ I was wondering the same thing - however you did it to get 31 was correct though squeak got the same thing. So what way did u do it?

I did 4 x 20. Assuming that 20" was the length of the port.
