In stead of the standard ‘offset driver’ To kill that second pipe resonance?
(I’m just being a nerd-geek)
the 3000cm2(90 liters) @30 cm and 500cm2 42cm port (~50 hz in the green graph )
verses the 3000cm2 offset at (~1/3) 107cm in 300total.

yes sir... i think ? or my dumb@ss is chasing my tail 😀
I dunno if Ibe got ‘apples to apples’, but Fb is The same in all of them
(top pic is the straight TL in white and the offset version in green )

Right, just the 3rd harmonic dip is offset due to pathlength differences between driver, vent.
