How does this ‘work’ ?

The acoustical path lengths/end corrections leave a big notch at/above 3 x Fb?

Because qw resonators are incredibly intersting when lined up to share(1/4 parallel to 3/4) or cancel(driver @ 1/3,2/3) a resonance ?

I don’t understand what this does ? it leaves me with an issue(hiccup) in electrical impedance as well as cancels freq response there

something is very hard on the drivers too? Random loadibg and resonances on either side of the cone Constantly ?

I dunno? Isnt this your design ‘turk 182?’

3:1 verses 4:1 path lengths. opens up a big notch? and lastly is without the added resonator in parallel.. (is it helpingaything, or just addig HF noise?) bose wave cannon(3:1) doesnt leave cancelation, etc or need to be stuffed with damping to try and dig out that notch?

5:1(closer to the rendered drawing)gets "worse" maybe?

I guess it’s like offset driver entry point in a TL at 1/5 or so? What’s the point if it doesn’t actually help with the 3/4 harmonic and 4/4 cancelation (~1/3) .

or create much ‘gain’ in the bandwidth to justify the ‘wasted space’ that coulda been deeper bass as a ‘normal tapped pipe/TL‘

I dunno? Do parallel Helmholtz resonators run into similar issues or is this the issue with long pipes and multiple resonances (1,3,5,7…) /cancellations (4,8…)?
