@kota1 My notes of several of the curves we have to deal with to get a coherent signal in our listening rooms is exactly on topic. @lonemountain said it perfectly "Active is not about where the amplifier is, it’s about where the crossover is." Absolutely!, Keeping timing issues coherent in audio is very difficult. It's more complicated that most everyone thinks even if you use DSP with all of your equipment on.
If you are listening to a wonderfully recorded live album in which the lead singer uses a wireless microphone that recording will have internal latency issues if that wireless mic is digital like the best wireless systems are, the latency in digital wireless mics varies depending on the version of microphones usually a production company has many of these mics lead vocals, backgrounds, etc. so the newer versions of these mics are different and uses updated digital circuits. So all that to say there are very few modern recordings that are phase coherent from the start, When I was recording movies and TV and some music I had to use a digital mixer that was able to put a delay on each channel of different digital and analog microphones, that is very difficult and I didn't know of any other production sound mixer who did that, I really worry about such things.
