Mark the linear-phase LR24 crossover experimental
...
The low frequency performance is too poor at this filter size and the
DSP load impact is too high. This needs to be implemented using FFT
convolution instead.

Fix phase response in the Crossover plugin
...
Didn't have time to do this, now I do. This nudges the phases from the
lower bands to match the higher bands, making the frequency response
magnitudes sum to unity again.
