Left side was delayed 1.7 milliseconds, with the left side -2 db in volume.
This gave me a stage that sounded centered right at my head...for the mids, but it was a little biased to the left side tweet, since it was RIGH THERE....so I moved that tweeter down to the bottom of the speaker grille, had to adjust my time alignment back to 1.5 milliseconds, and the left side is only reduced -1 db.
This gives me a sound stage that is centered smack infront of me when Im driving, and extends out the the right and left evenly...
It could use some more tweeking, but without some major mods to the doors for better speaker aiming, its not going to happen...

So this is why Brypink suggested that I get the H701 when it was 1/2 price. I messed up
