Does measurements really matter?

They matter a lot to some people and matter not a jot to others (like me) - it's all good.... 

Well, if we ever hope to hear recordings as their creators devised them, yes, of course they do matter.

Otherwise we risk forever going around in the audio circle of confusion that Sean Olive and Floyd Toole have spoken about.

Whatever you or I decide to sonically do with that recording afterwards is entirely up to us, our ears, our system and our room.

An excellent video. Harley does a great job discussing the place of measurements in recording, design, and playback. I am a trained scientist and worked as a electro / mechanical design engineer. I quickly realized principles and specs would get you in the ball park… but quickly needed to be abandoned and experiment with materials to get the preferred outcome. Just like I have heard high end audio designers say… these resisters sound like this, these capacitors sound warmer…etc… and they go on to craft a natural realistic sound and leave the specs take care of themselves. I guess, that was one of the first lessons I learned after buying some amp with incredible peak watts per channel and sounded terrible. A real basic principle of high audio… glance at the specs…. Then listen, listen, listen.

If you're going to listen to single driver slim tall boxes they don't matter at all. 

Watch Danny Richie's GR Research You Tube videos to see what and how he measures loudspeakers. Very similar to what John Atkinson does.
