One slight problem with that, in case you haven't figured them out already:
How would you determine which Great Speakers to use to generate your curve? Also, did it occur to you that "great speakers" are generally regarded as "great" due to the listener preferences?
I think that's a rather artificial barrier.
Especially as you're using to support Harman...who based their initial curve on those same great speakers.
Look, I see it like this. At some point the music, whether held digitally, or on a tape, or a record, or whatever, has to enter the real world, and that's through speakers.
Yes, you won't get everyone to agree on what a great pair of speakers is. But if you get some which are as flat as possible, and place them in a 'real' room (not an anechoic chamber), you're surely 95% of the way there. I suspect that, if you got the 'ten best' full range speakers in the world, level matched, in the same great room, whilst they wouldn't sound identical, I suspect they'd sound broadly similar.
