Interesting speculation, and I watched the same GT interview and have even discussed this topic with Erin directly. I really want to find away to objectively quantify or are least suggest objectively measured what I and other have heard.
I'm not sure what what/who you are responding to as this thread has majorly wondered but I attribute the difference more to the wide baffle width of the JBL at this point and much more controlled / narrow directivity of the JBL vs nearly omnidirectional Revels.
It not obvious as I don't get what you're trying to say here and thus your post isn't helpful. I'm coming here for honest open discussion not snarky remarks that obviously add nothing to the discussion.
