    Your approach is to match each driver to the target curve or match left then right then both to target curve?

    Both, I think?

    I match each to the target curve individually using a microphone.
    Then I do a bunch of other stuff.
    Then I try to match left VS right by ear using bandwidth limited pink noise (by ear).

    Very very similar to what Jdunk describes.

    But again, this is not the one true best way. It works well for me, and I find it's fairly easy to teach someone, but you are welcome to use whatever method works well for you.
    Measure with mics, mark with chalk, cut with torch, grind to fit, sand to finish, paint to match.

    What i find cumbersome with matching each driver to a target is when you want to change tonality and don't have a global EQ you basically have to retune everything affected by the overall tonality change.
    Therefor i roughly match the drivers to a base curve and do the rest with a global EQ that keeps relative phase between drivers in check, f.e. make the slopes as good as possible with the driver filters and let the global EQ deal with the passband anomalies.
    This way you can easily change the tonality with the global EQ.

    What head unit doesn't have a global eq of at least bass and treble? Sometimes bass mid and treble or more. Best global eq because it is right at your fingertips! My friends nissan sentra has one of the best. Bass is a low shelf around 100hz and treble is just a title control!

    That is also one of the nicer things about the virtual channels on the helix.
