[QUOTE="Ivan Beaver, post: 141947, member: 30"] Re: Danley SH96HO Let me explain just a small part of the "design process" of a passive crossover. First we gather individual amplitude-phase-impedance curves of each pass band. Then we start to design a crossover to get the "ballpark" response curve we want for each passband. It is when we PUT THEM TOGETHER, that we start to change all sorts of things-freq/slopes sometimes eq (yes passive eq) and so forth. At that point we are not so much concerned with the individual passbands, but rather the system as a WHOLE. We do constantly monitor the electrical response of each band to make sure that things don't go beyond where they are safe. If so, we back up and redo. At no time are we concerned with a "simply number" or a single "crossover freq". We are looking for the overall response. In a good design, you cannot tell where the crossover point it. That is a GOOD THING, and it doesn't matter. In a "perfect design, it wil look like a single driver loudspeaker, with a phase response that looks like an electrical HP/LP filter combination. Sometimes we get closer than others. [/QUOTE]
