Dear all,

sorry, I am too dumb for digital filters!

The Linkwitz-Riley 4th order filter is not
a 4th order butterworth filter, but a
cascade of two second order butterworth

Hence I must not take the coefficients of a 4th
order butterworth, but convolve the 2nd order
coefficients instead.  This is correctly done
in sox.

Sorry about the false alarm.

            Best regards,
