You aren't agreeing with me or disagreeing with me, it's physics both pure and applied that we are forced to agree with.
Yall can measure internet dicks all you want, to my ears 10's sound better than 15's for bass. Maybe it's the cab, speaker design, room, planets lining up, I couldn't care less. 10's = better.
Bass and guitar amp and loudspeaker technologies are principle different.
Guitar amp has high distortion and low damping factor, uses high resonance speakers with limited frequency range, and many case - open back boxes.
Bass equipment is much closer to hifi or pro-audio gear.
I once built a pair of line source speakers. 8x 8" drivers in each IIRC and they were paralled in pairs to give 4R and then four 100V line transformers used to get them back to the 100V o/p amp.
They were frigging heavy columns but loud and clean as ***t!
Serial connection kills damping factor, and it is what guitar amp needs, and bass amp no.
If there is such possibility to switch loudspeakers in serial and parallel (for example - 2 x 8ohms in 16ohms or in 4 ohms) and there are switchable or separated 16/8/4 ohm amp outs - try and compare 16 ohm with 4 ohm versions on guitar, serial 16 ohms will win !
Open back box is additional factor to lower damping and resonances, open box never will be boomy.
Concerning bass - only parallel loudspeaker connection (Ampeg uses 32ohm speakers for it), and closed or vented/resonator box.

The cabinet is too small for 4 12 inchers. The panels are left to resonate with almost no stiffening or damping material. It is a closed box but far from airtight and, as you say, each driver "sees" the impedance of the other when in 16Ohm mode which is the preffered mode because that is what would have been used historically ("proper" power amps and speakers were always 15aka 16 Ohms in the begining). It also uses all the copper in the transformer and is thus more efficient...BUT!..
The SOUND of this leaky, rattly box is the one our gonads equate with rock and roll!
