[QUOTE="john lutz, post: 58560, member: 244"] Re: Voicing/tuning a 3-way home brew speaker cab Thanks all for the input - your suggestions, based as they are on lots of experience, are very helpful. I know polishing an old rock box is pretty far below what most of you do. I already see I'm going to have to access the user forums on the software I'm using to try to figure out the phase trace functions. Very hard to get understandable results ! Moving the mic or changing the delay / xover causes displays I can't interpret. The frequency response and impulse response functions are pretty straight forward though. Some questions: As I measure the 3 sections I see the delay of each in impulse graph. What am I looking at? Is that group delay? Or physical offset? Or both? If I then apply xovers and delays to each section and line up all the impulses, what have I really accomplished? It appears to smooth out summation - sort of - sometimes............ this is fun.
