The L3 features a linearphase crossover which doesn't introduce phase distortion between the frequency bands. The crossover points are selectable by the user.
L3特有的线性相位交点可以保证在常用波段之间不产生失真，而交点是由用户选定的。

This paper defines phase and group delay distortion of audio system based on point view of linear system analysis and the physical meanings of group delay is discussed.
本文从线性系统分析的角度定义了音响系统的相位和群延迟失真，并讨论了所定义的群延迟物理意义。

However, if the phase change is non-linear, then the non-sinusoidal signals will have a serious phasedistortion.
