Default Preamp low pass filter

You can keep the low-pass and high-pass outputs in phase
with a 4th-order filter.



Not without an additional all-pass filter you can't. And with an added
all-pass you can make a second order crossover have no phase difference
between the LP and HP sections if you want.
