Hi, now I’m almost at the end of my expansion and soon I’ve connected everything. Now I want to adjust everything rationally. Unfortunately, I don’t have a plan yet where I have to separate what and how I can test what is best for me. How can I set an exact separation frequency with a small poti at the level? There’s nothing exactly on it. Since I have a Q 22 each, the two should be set exactly the same but how do I do it? Please help me. How should the front system be tuned? I have installed an active crossover and that is the one of Sony XEC 505 or something like that. With this I can still adjust a lot from the front but I have to adjust the power levels first. What exactly does low pass and what high pass mean? What do I have to dial? I have always set it up until I found it good but I never took the meaning to heart.
