To study the effects of the audibility of retaining absolute polarity it is useful to have an asymmetrical waveform (see link for examples). But I was thinking about this and was noting that you really have to watch out not to clip the signal within an amplifier in the system - I was going to use headphones for the listening test. If an Asymmetrical waveform clips on the "larger" side signal - the device it is driving is going to see a DC offset voltage - essentially moving the driver out of the center of it's gap causing likely audible distortion. A multi-way loudspeaker high passed devices will go unaffected - but the woofer and its inductor coils will be effected. probably noticeably. If sufficient in amplitude it could damage the loudspeaker. Just think how much a 1.5 volt battery causes a woofer to move.While playing music, it may be more likely that a woofer is damaged that a tweeter with amplifier clipping! And certainly the audible effect of the clipping will be greater as the woofer (that reproduces the primary fundamentals and overtones of the music we listen to operates non linearly...
