Group delay in this case is maximum around 2-3ms for HF and around 4ms for MF. It seems too high compared to maximum around 1ms for LR4. According to some studies more then 1ms in area of 500-5000 Hz could be audible. My idea is to make very steep crossover around 72db/octave for both crossover points in 3way and Group delay not higher then 1ms in 50-20kHz band. Could you suggest which type of crossover I should choose. Maybe instead brickwall I should use LR12
