MC, I got it!!!! Clever and fun.
More seriously, size not critical - but only nowadays. Design and new tech are changing the old parameters.
A big sound depends on how much air is moved forwards. So this meant earlier large cone size vs breakup was the issue. Larger and stiffer=more bass directed forwards.
Nowadays with high excursions being permitted by the new materiels, and some creative thinking, it's possible to get smaller cones (almost zero breakup) to do similar stuff.
A recent development has been to design the speakers port so the back wave is phased to reinforce the front. Eg D&D, some open baffle designs.
Kii use a slightly diff approach. They have a back speaker which slightly out of phase so that it cancels the front wave behind the speaker and reinforces it in front of the speaker. Along with dsp and long throw cones their speakers measure down to 19 -20 in room +- 0.5 dB!
KEF's new approach is to simply cancel the back wave internally - with no consequent penalties. That is unbelievable in my book but they claim to have done it.
So the answer to your question is that the new slightly larger bass drivers may improve bass response, but you should look at these new technologies first, if possible.
Best wishes
