As much as I respect this idea, I don't think it's useful for any real-world applications. If I've learned anything concrete in all my years as an audiophile, it's that we all hear differently. We all have different rooms and partnering gear, so speaker recommendations based solely on a price range are useless, mostly.
Even the pro reviewer lists (Stereophile) are generally useless IME. There is a wide range of performance among the same "class" of speakers. For example, the "class B" Stirling Broadcast LS3/6 far surpasses the class B Monitor Audio Silver 8s in resolution, imaging, and overall musicality - so much so that I would have placed them at least two classes apart (I've owned both), even with my most modest partnering gear.
I recently preferred an old pair of New Large Advents to a brand-new pair of popular and highly-regarded $3K speakers (and by a wide margin). Similar Advents can be bought for $250 - $400 on fleaBay, so I guess you can add those to both the [under $1000] and [$1000 - $5000] lists.
