[QUOTE="Mark DeArman, post: 57903, member: 950"] Re: Intermod distortion 2-way vs 3-way Well phase response is a global quantity of a linear measurement. It doesn't really have anything to do with non-linear behavior. I have found that a typical loudspeaker can be broken down into at least 5 mono components in a two way system. Next Thoughts on the Thread: Lets say our speaker system is properly built. The source drivers are at distances consistent with their cross-over frequencies. Wont a 3-way, 4-way system suffer the same type distortions, although not identical, to a two-way system? Other Thoughts on speaker designs: This brings up another thought I have been having about Coax boxes of late. Is the distortion caused by putting a fixed horn in front of a cone loudspeaker better than the distortion caused by the cone working as the horn/wave-guide? Trade-offs abound in this area of design. As for the two-way+ cabinet; A simple experiment to be done.... Power one of the drivers and measure the voltage generated by the other drivers in a cabinet. There is no real damping provided beyond resonance so this should be a good indicator of how much pressure is coupling to the other drivers. Any other thoughts on that? Anyone want to comment on non-linear loudspeaker measurements? I do have a tool I have made recently, never used yet for any speakers, which I will post later. It's not dependent on the input being a frequency response derived by linear methods. In fact the best input would be a linear sweep which would show the difference from linear IF.
