Have you ever run a square wave through a 3rd order Butterworth filter tuned to 50Hz? Have you really seen no phase shift at higher frequencies, say in the 800-1KhZ range?
Furthermore, why do some loudspeaker designers (who know their stuff) fuss so much about sub woofer integration when the frequencies are generally below 100Hz? Bases on your response, it would seem to that it wouldn't matter much due to the size of the wavelength. Maybe you know something that they don'?
