I have a pair of L36, I came across your posts (great job). I copied your x/over except that I used Jantzen Standard Z for the LF.
I seen a post where you said you had the presence and brilliance adjusted way down. I experience the same thing. And even with the adjustment some songs still should too bright.
My question - did you ever tweak the crossover? What did you try and did it help? Where you happy?
