@sozocaps , if you are going to do this do it right. Analog crossovers always have issues and are not very flexible. You can not adjust group delays. Digital active crossovers that operate in 24/192 or above are far superior. Check out DEQX's soon to be released Pre 8. It actually has a full 4 way crossover so you can add a sub if you like and it will test each driver and correct them all in time and phase. It will also establish a flat frequency response and from there you can adjust it for taste. This is the current state of the art and it is not insanely expensive.
