Effect of balanced input on harmonic signature of Pass/FW amps

[Quard]

Quick but deeply felt thanks to everyone who covered the input amp vs power amp character question (really nicely for greenhorn like me)

brought to mind a dumb question more Mega-dumb (because that's my burden) than Pico-,
does character of speaker driver 2H mess with pos-vs-neg characteristic of amp?

Sure, lotta driver spec sheets show how much 2H, is there a way to decipher what character (pos or neg) driver 2H might be? or general rule of thumb?
I dunno, does driver size have a usual effect (pos vs neg) for various frequency ranges/diameter or something? or mebbe driver 2H is always positive, always, always, always, dodo, or something like that?

Thanks in advance to anyone who can decipher this stab in the dark from a flightless tropical-island-wanna-burd...

I missed this memo.

I read that.
I bought only a pair.
Didn’t know I needed a quad.

...in which case, expensive fancy-pants low-2H(pos) driver can still partake of partial 2H(neg) sweetness of specifically-spekked amp
whereas low-price Godzilla-footed high-2H(pos) driver will bambi-mom the gentle 2H(neg) sweetness of specifically-spekked amp design
out of existence with its weighty high-2H(pos) footprint to leave Bambi-kin unnoticed amid the thick, but red-tinged Jurassic mud left behind to ossify one' ears...
or maybe you just gotta keep cranking up P3 until you hear the difference?

There are nice designs needing only one vfet per channel.

👆What he said. I bought extra just in case. Figured if I didn’t use all 4 someone here would use the leftovers.
