А ты никогда не мерял микрофоном АЧХ) Изменения которые зависят от громкости это галлюцинации мозга, а не изменения работы динамика.

... и добавил:

не надо мешать мух с котлетами

усилок меняет свои характеристики от громкости (подгружается)
динамик не меняет параметры до тех пор пока на максимум не выведешь
слух по разному воспринимает звук если меняется громкость, даже если параметры звука при этом не меняется

Т.е. фраза "раскочегарить динамик" неверна.
Раскочегарить можно усилок, или просто навалить громкости чтобы мозг охерел, но динамик не меняет своих параметров от громкости.

Ты любишь замерять АЧХ. Берёшь любую железную пластину, ставишь микрофон и ударяешь щелбаном, а потом молотком.
Если у тебя получится одинаковый (тот же) спектр гармоник, я тебя поздравляю, ты человек молоточный щелбан. Вызывай Гиннесса, фиксируй достижение.

я тебе чуть видоизменю задачу чтобы ты понял свою ошибку
Берёшь струну щипаешь пальцем, а потом бьёшь со всей силы медиатором.
Разница только в громкости (амплитуда). Нота (частота колебаний) не изменится

и повежливей общайся, щегол, свои достижения фиксируй
даже если ты вдруг почувствовал свою правоту - не повод неуважительно общаться

When driven hard, guitar speakers produce complex behavior, which affects the sound of the instrument. There will be some power compression, several kinds of distortion, even mechanical limiting as one or more drivers approach their physical limits (e.g. cone excursion). A guitar speaker shows a nonlinear frequency response depending on the speaker's load, e.g. the frequency response, and various distortions, at small amplitudes is different from those at large amplitudes.

The first noticeable point is when yo slowly turn an amp up from nothing and it's all thin and wimpy, and suddenly it gets loud. That's the point when a speaker membrane really gets excited by the driving signal.
Then at some point, especially with old fender amps, you get cabinet involvement, when all the wimpy boards that are loosely screwed together start to shake, rattle and roll. (PA speaker cabs are so much more rigid and stable in comparison.)
Then some speakers start to saturate and distort, which generates overtones, when some frequency bands get squashed, because the speaker can't push the air harder in a linear manner.
Then there is cone cry, which is the speaker itself resonating an generating noise when pushed close to it's limits of power handling.

Guitar speakers are very nonlinear in their behavior.
It's not an easy "at 50W you get this", but it all depends on the individual speaker, the cab, the impedance coupling with the power amp and the signal you are driving it with.
e.g. a speaker that handles a 50W 1kHz sine wave very well could totally get whacky pummeled with 50W of downtuned dual-rectified powerchords...

It's one of the reasons I think IRs of alnico speakers never sound or feel right to me. It's not hard to hear how an alnico blue compresses and reacts to transients at low vs high volume, and to be fair it's also a thing with ceramic greenbacks. An IR isn't dynamic in that sense.

I think once you get into the realm of putting two or 4 high wattage speakers in a cab, it's practically not going to matter loads. Because even over quite a wide volume range, the difference of putting say 15 or 50 watts of power into a cab that's rated for 200W+ might feel like it should really matter, but 15 watts is enough to get the speaker cones moving nicely and 50 watts isn't even going to make them break a sweat. It's just not gonna be the same demonstrable effect over the practical range of powers you'll use vs when it's a 100w marshall into 100w cab, or 30 watt combo into two 15 watt speakers.

Then there's the amp-speaker interaction. It's not a one way street - the speakers can be more or less dampened by the design of the power section. If all else could be equal, 50 watts into a cab wired in series with no negative feedback in the power section would make the speakers respond differently to 50 watts into that same cab wired in parallel and negative feedback in the power section.

Really, the devil is in the details and the answer's gonna change depending on the rig.
