Hi all, Just wondering how i would go about Calibrating my 10" Velodyne Sub. What do i set the following to: Knob 1: Low pass Crossover - goes from 40hz to 120 hz Knob 2: subwoofer volume Then there is also the "phase" and "internal x-over" Also the "high-pass crossover" which is either 80hz or 100hz. I have a Yamaha 5450 receiver. For the front speakers i have JBL N26, but as of tommorow i think i'm going to get the JBL ND310II. My backs right now are N24's but if i get the ND310II then i will use the N26's as the back and one of my N24's as the 6th speaker. My center is the JBL N-center. So i know with my sound pressure reader i want the sub test volume to be 80DB (from reading the forums). But where do i begin? Where should i set the knobs? do i put the high pass crossover at 80 or 100? Should i put my BASS volume on the receiver at 0 then turn up the knob VOLUME on the sub until i'm reading 80DB....or? If so then where do i set "low pass crossover" to? Thanks a ton guys.
