For each frequency (j\omega), the vectors from pole and zero have equal magnitude → unity gain. The phase difference between the two vectors gives the net phase shift.

Modern loudspeakers are complex mechanical systems. Often, the woofer (bass) and tweeter (treble) are physically misaligned on the speaker baffle, causing "phase distortion"—a situation where the sound from the woofer arrives at your ears slightly later than the sound from the tweeter at the crossover point. allpassphase

Understanding the All-Pass Phase: Theory, Applications, and Filter Design For each frequency (j\omega), the vectors from pole

Are you designing this for or data communication ? Often, the woofer (bass) and tweeter (treble) are

H(z)=z-1−a1−az-1cap H open paren z close paren equals the fraction with numerator z to the negative 1 power minus a and denominator 1 minus a z to the negative 1 power end-fraction

You cannot replace a linear phase EQ with an allpassphase network—they solve opposite problems.
