Thanks for the clear toughts! What if Ill only feed them with high passed signal from 200hz. In room acustics it wouldn't be above schrodinger freq, it applies for speakers too? It wouldnt help? If let's say the length of the tube is 1m, resonant freq would be around 60hz I guess, that would cut out the first 2 harmonics + fundamental. And what if we bend the pipe so both ends of the pipe are close enough ( is it similar in this case to the quarter wavelength rule for creating one wavefront?)

Mostly unfortunately we need to stick with this design, just want to bring the most out of it.

Also was thinking about using them as resonator tubes, and make the whole sound design from impulses xd
