Yes, but less important when you are using wall loading as Josh is doing as dipole cancellation is restricted on one side. .

I'm just establishing the principle. And Yes, with the panel using wall loading, that side is pretty much 'out of play'.
The reason I ask is that I've seen Panels with 'truncated' frames (Apogee?) which I suspect varies the cancelation frequency. Advantage? Disadvantage?
I would design such frames for my 1.6s, if I ever work up the energy to start!
Too much is never enough
The trapezoid shaped frame on the Apogee is supposed to spread the baffle loading over a broader range of frequencies rather than have the one freq below which it just falls off.. Other issues are at play but I don't remember what they were. That should complement the room's bass loading and provide a more uniform bass FR - it is sort of a substitute for Magnepan's resonance freq tuning with the buttons. but operates at a different freq range to provide a lower bass emphasis vs more even response on through the midbass on maggies.
I don't expect it would contribute to a maggie reframing project. .
