I have a length of 14.5" OD poly tube, approx 7'
and I have approx 6' of 12.5" OD poly tube.
I've roughly calculated approx 24 sq inches of "port area" between the two cylinders if they were nested. 5.5 in diameter is what I'm guessing is the equivalent in tube size if I was to calculate this area as a port.
anyone wish to discuss using a 10" driver of some kind for a multi-media subwoofer with these materials?
