[QUOTE="Mark DeArman, post: 57954, member: 950"] Re: Intermod distortion 2-way vs 3-way Haha, man I must have been really drinking when I wrote that. You're completely right. Drivers only vibrate near resonance or high impedance when they are "shorted" ie. connected to an amplifier. The real experiment is to measure the cone motion. Well that wasn't what I was wondering about regarding coaxes. It's not really about sound getting into the other components. It's about whether the cone moving effects the HF more than the horn body effects the LF-MF from the speaker. More in regards to my tool photos. It is actually pretty neat. If the system is linear you should be able to slide all of the pulses together on the 3d graph with all-pass filters, and when you do that, the system should be minimum phase and linear phase. If you can't slide them together then something else is at play. No FFTs involved although it does agree pretty well with a spectrogram and WVD. It's just not showing Fourier 'frequency' on the y-axis. [/QUOTE]
