[QUOTE="arwolc, post: 8692205, member: 678645"] Hello. I have Hertz EV165.5 mids. I want to make low pass cross(I have made it already(3rd order butterworth 750Hz). I test it with Phone aplication mic(db meter), I have no other special mic. I have a problem, from 200-750(800)hz is flat line(all ok), after 800Hz, starting to fall down this db line, but where is 850-900 is a bump with +5db and continues till 1800Hz. I made 3rd butterworth, I add Zobel, but no changes. Could someone help me, please? Or I need DSP and thats all? :) [/QUOTE]
