As we all learned in college, very few things are proven, just strong supported or not. I guess you mean what tangle measurement can one produce to support that a given speaker is better than another, with as little i harem you as possible.
rather than trying to provide this, I just search for the sound that suits my taste. I will leave the proving to someone much more technical than me.
