Did you also notice any phase and/or reflection-related issues when playing L+R speaker pairs? For example, my left dash and right dash measurements would be spot-on (to my curve), but when I played both left and right dash speakers together, the result was no longer "spot-on" with my curve (due to phase and/or reflection issues) - i would have some wide, shallow dips at certain areas. :-)
Obviously, your ears are the ultimate "measurement" - but you never know - you may be able to improve things even further if you can identify and fix ever more issues. "You don't know what you don't know" type of thing. :-) Which is the whole point of this thread - to look into identifying and resolving some of these issues.
You can really only get the full picture if you take individual, L+R pair, "all speaker" and even left/right side measurements - and see how they all interact with each other. I've found it pretty interesting how things change when multiple speakers are playing (vs just measuring individual speakers or "just left" / "just right" measurements). Another example - my left and right midbass speaker measurements will be perfect individually, but when played together, I get a very narrow 7dB dip at 421hz (which I honestly just ignore in this case - at least so far). :-) Also, 1/3rd smoothing really won't show that narrow dip, but no smoothing will show it very obviously.
Obviously, another question is whether or not you can actually hear a lot of these "issues". Although, to me, I just figure that if I can fix them, then why not?
