Well, when doing a BR, what do you wind up with? 
A relatively small cab/long, big vent 
= inverse tapered TQWT. 😉 No fooling Mother Nature 
as we're always 'robbing Peter to pay Paul' to get the necessary net Vb for a given gain BW.
Right, though make sure you understand woofer speed WRT Le, Mms because it's a perennially misunderstood subject as proven here.
Yeah, a typical vehicle's interior minimal damping even way back when in my El Camino's interior forced me to use under dash/angled up and 'x' crossed (toe'd in) wide range RadioShack prosound horns run 'wide open' (max efficiency, hi-passed as low as the SO's keen hearing could tolerate) to bring the 6x9 tri-ax 'FR' driver's 'sweet spot' from down behind the bench seat 'forward' to get the sound field in front of, and up high enough for us to get what at the time passed for a 'you are there' stereo performance.
In today's near tomb like interiors I imagine it would take a bessel array above the windshield to get similar, but yet to see even a mention, much less someone actually trying it.

Sound-wise it's all about the 'quality' of the damping, though 'critically' damping the vent makes it near enough a 'six of one, half dozen of another' scenario, leaving only the (usually) allowing a larger/greater acoustically eff. vent and more optimal driver/floor location options.

What ‘good’ is offsetting the port in a TL? It seems it just puts the vent at a lesser vmax /exciteation for the resonances…. But it also creates another resonator/stub that messes everything up further?
thanks for always entertaining my silly questions so I don’t waste as much wood 😝

Well, the pioneers learned that 'driver in vent' was the ideal for their need for maximizing acoustic efficiency and later even put them close to the driver in high aspect ratio cabs to get some BSC and me n' others have moved it at various offsets to better blend in room relative to the listening position (LP), which in my case almost always meant tuning each speaker individually in room, so best not to design in a 'vacuum' for max in room performance. 😉
