It’s just a subwoofer, so the crossover is @ 65-80 hz, but is there any benefit to offsetting the driver position to the pipe resonance other than the obvious affect at the higher freqs? (The vent and driver are in the same position as well?)

I made a smaller version/test box with tangband 5” drivers and cut a hole in both ends of that big first fold/chamber to see what happened with a driver at either or both positions. That pipe resonace is REALLY loud if the driver is at the closed end or if two drivers are installed
