Great post with which i concur... Thanks...
A lot of good answers here. I've been working with measuring and listening for the last week, listening and noticing what I don't like, and then trying to understand how to fix it. Measurements help get me in the ballpark. I know what a really bad sounding measurement looks like. What's harder to tell is what a really good sound measurement looks like compared to a decent sounding measurement. There are a lot of different ways a system can sound good or bad. If I move my crossover for my tweeters from 600 Hz to 1000 Hz I can get more headroom and dynamics at the price of less natural tonal character because the dispersion isn't as smooth. I also get better imaging in some ways with the higher crossover because it gets beamy between 600 and 1000 Hz. The measurements show lower distortion at high volume and better in room clarity at the higher crossover. My ears tell me the tonal quality matters more.
