Not really purely subjective. The improvements gained from large woofers over small are easily measured.Subjectively, this is my experience too. I hate to mention such a subjective belief/theory on ASR, but I am a believer in this.

I know that cone breakup (a potential downside of larger cones if not crossed over properly, right?) is pretty easily seen in FR graphs.

It's the distortion of the driver itself. The physical ability to extend to lower frequency which is hard to achieve with smaller size.Hmmm...
Max spl: Yes, for sure. But, the benefits seem apparent even nowhere near high SPLs? I've never done blind speaker comparisons, though. So my impressions are surely biased.
Flatness of bass: This is trivial to achieve via DSP on any speaker, though, right? (And is going to be highly room-dependent anyway, without DSP)
Harmonic distortion of bass: This makes 100% sense to me. Though, you so seldom see measurements for speaker THD. I think amplifier load plays a big issue here. Larger woofers tend to be more efficient, and therefore can present an easier load to the amp?
Ah, what they said ^I'd like to know more about this. How are they measured?
If I wanted to do distortion measurements for my drivers what equipment would I need and how would I go about doing so? There does seem to be some fairly comprehensive measurements available for my speakers here but I'd like to verify them myself with my own hands. Scroll down to the bottom portion of the review and you can see them.
I wholeheartedly agree with HammerSandwhich above me. What I came to realize having jumped from KEF LS50, to Harbeth 30.2, and Arteluthe Cadenza, was that bigger drivers equates to bigger sound. The swiftness and accuracy of percussion can't be replicated to the extent it can be on a large woofer. I do believe it has something to do with distortion... and I as well cannot explain why.
Is the bench meant to be the listening position? Going to be very little crosstalk between the channels like that.Smaller cone area has lower acoustic efficiency (coupling to air), it's one reason for higher distortion in addition to T/S limits. The small cone sort of slips and slides in the air instead of pumping it effectively. Sound volume/dB means air pressure variation, and a driver's air volume displacement capacity is crucial. Compensating membrane area with high excursion leads to many problems. Horn loading is a smart way to improve efficiency/coupling, but for bass the size of the horn needed is huge.
Loading down to 30Hz
