The design I chose requires a 6" diameter port, 33.5 inches long.
I'm having a bit of trouble fiding a 6" diameter PVC pipe.
According to WinISD, I would get the same tunning frequency using two 4" diameter ports, 30.75 inches long. Does this sound reasonable?
If not, What length of the 4" diameter ports would get me the same tuning frequency?
thanks
