From someone that has little interest in getting to this point of capabilities of speaker measurements. I thank you for the post. I am in the 99.999% of listeners that enjoy good sound but have no equipment to measure what they are hearing. Am I considered an audiophile if I am seeking good sound, or am I considered an audiophile if I have the ability to electronically measure equipment. Or is an audiophile an electrical engineer that likes his job? this is the first video I've seen that actually explains what the measurements can indicate a speakers capabilities. (no, I haven't looked at all let alone very hard). I'm curios how much an adequate set of measuring equipment would cost?
