Try Pipe organ design. Gives you the input to cut the tube to any audio

Has anyone built the resonator with a straight length of tube? Perhaps
terminated with a 45 deg. cut?
Might be an interesting experiment.
The 45 deg long radius street elbow in 2" is an order only item in my area so
thought I'd substitute a straight length.
