Maybe the word "distortion" is the wrong word to use here.
Saying "The relative phase of two drivers outputting sound at the same frequency" (as happens at the crossover) may be a better way of describing one of the problems that often occurs in speakers. When the tweeter and mid/woofer are out of phase with each other it doesn't sound right and spoils the sound IME.
