Even better crossover would be in digital domain. For example today most source music files are stored in personal computer. Before otput on PC USB music content can be filtered for LOW,MID and HIGH frequency. Separate I2S signal should go out from USB. But in that case we need 3 DAC's (3way) or 4 (4 way). Such crossover will avoid all problems with noise and distortion produced in crossover OPAMP's.
Another option is to use 3 or 4 DAC's in parallel with crossover filter loaded in DAC. DAC like Soekris DAM 1021. But so far nobody realised such crossover.
This is just my thinking about ideal crossover.
