Great stuff, I had a flick through. I wouldn’t recommend going above 18dB/Oct, 24dB/oct max (especially in higher frequencies where we are more noticeably sensitive to phase change). Or at least not without crossover phase compensation to make it linear. The phase change otherwise is just too high to be worth the extra steepness. If you do use the steeper slopes with minimal taps compensation we have available here, I’d recommend that this should be alright (but not ideal) if the phase was just linearised to 90° or less anywhere above -40dB from the fundamental.
