[QUOTE="Silas Pradetto, post: 81041, member: 34"] Re: Using crossover filters on X32 Crossover design is something a bit more complicated than I can describe in a single post. Each slope imparts a different amount of phase shift at the crossover point, and it can affect the overall polarity of the signal outside of the crossover region as well. By far the most common crossover design is using symmetrical LR24 crossovers on the low pass of the sub and high pass of whatever full range box is adjacent to it, but just because it is the most common does not mean it is the best. Crossover frequencies for real subs is often at 80Hz or maybe even lower, but as high as 100Hz is common also. Remember that the crossover frequency number has little to do with the acoustical crossover, which can be seen with measurement. Most often, the acoustical crossover is higher than the numeric crossover because subs are run much hotter than tops, relatively speaking. Running aux fed subs gives you an extra variable, since the relative level of subs to tops is now able to be varied easily. You have to realize that crossover design is something highly measurement-dependent and could even change based on physical speaker locations. Always remember, "If it sounds good, it is good."
