Re: Virtual SMAART training: Explanation Slide 3Hi Phil,What I don't understand is there is a step in the phase response of 180 degrees from +90 to -90 at the crossover (2K). There also seems to be a corresponding dip in the amplitude response where things aren’t summing too well. I would have assumed that QSC would have matched the phase and required delay nicely through the crossover. The apparent difference in arrival times of the HF and LF drivers seemed too much if it was related to your measurement being a little off axis. I must confess I wondered if the polarity of the HF driver was wrong, but it seemed unlikely on both boxes. I also wondered if it was a QSC K series that someone had reversed the HF driver polarity as has been discussed on some websites. Peter
