I believe that as long as you sport this notion of liking and buying the speaker you like, you're confusing the box for the art. I believe speakers should finally be relocated to the technology department and stopped being treated as art or expression of an artist. They have a job to do, not much different from a bike.
I could agree we're not there yet, but I would add that I think the journey is worth taking. I could agree measurements are not as accurate as one might hope (do not tell the whole story), but I wouldn't give up on this idea just because we need more accurate measurements. Also, I could agree that all this business of, let's call it a proposal of a unified speaker, is to a certain extent imposing itself on the market and colonizing it, but I think that the goal is a good one and one to be desired => producers mix and master sound with a known variable (certain type of a speaker), they get to know what type of reproducing equipment they're doing their job for and they can start producing material that will have a much higher possibility of sounding good.
Some companies will come to an end, but I don't think this will be the end of companies that mystify technology as there will always be people who mystify it.
This is the crack where, I believe, ego steps in; no one can know what someone else hears, whatever the reason for hearing something may be, market steps in and start fondling your ego telling you that what you hear proves you're exceptional in some way and no one can resist this siren's song. So your ego tells you; yes, you're exceptional and THAT'S why you can't be satisfied with mass produced AVR's, you need something a lil' extra. Special speakers for my special little guy!
Also, I don't think that esoteric and exclusive companies would have problems. They might as well stop lying to the people and just do what they do with furniture - if a sofa can cost 8k$ so can pretty designed and shaped speakers (using the word designed here like in fashion; colours, shapes, materials...)
