[QUOTE="John Roberts, post: 99009, member: 126"] Re: Prediction: visualizing phase contours I think magnitude response is most important but agree being well behaved is more important than being ruler flat. The problem with trying to perfect magnitude response with conventional measurement systems is that magnitude is a one dimensional measurement (or two with level vs time), but sound in a 3 dimensional space is more complex than that. We are all familiar the automatic EQ functions that sound like crap despite flat response for some measurement point. Phase response errors that cause bumps or notches, have caused magnitude errors. The cillia in our ears wiggle in response to magnitude not phase or arrival time. That is a post processing matter inside our grey machinery. All else equal phase should be managed too (after amplitude). I think one of the more promising things about the Danley speakers is their attention to how drivers combine with each other, promising both good amplitude and phase response. JR [/QUOTE]
