Hi FF, thanks for your interest (and sorry for the way things sometime go).
I thought one of your most pertinent points,

went all but unnoticed, by the way, and promptly went another direction. About a hundred times a year a similar question as yours is asked and notwithstanding the name of the forum, a few hundred replies energetically speculate and estimate.
If comparing, the solution is to either look for direct head to head comparisons from known sources or simply try one yourself. It's always been that way and so far, looks like it'll continue being the way to know for sure. Oh, and things that look
similar (or dis
similar) might not be, price points included.

Acoustical size is fundamental to the loudspeaker. (Despite making 5.25" systems - albeit with multiple drivers and double-duty XBL^2 - we've said that on the site for years, mostly because things that look similar but are fundamentally different end up mentally side by side, like boxes with drivers two sizes apart, for example.)
Size class is one way to generally differentiate visual comparisons and the conclusions inferred from them. However in the case where the system's acoustical size is to a large degree found in the bass speaker - going back to FF's original comment - then we refer to other things. Then the class size recedes in importance and a knowledge of how other things work could inform our speculations.
I wish you the best of outcomes, FF, and sorry for the diversions. This is where every once in a while a company might offer to at least try to privately clear up this or that basic point as objectively as can be done.
