speaker distortion

Can anyone explain how input current distortion as demonstrated in this video may or may not be important? Does it translate into distorted sound, independent of the amplifier being used for example? Also is it a measurement result which is offered by any speaker unit manufacturers? And should...

Hi, Im trying to improve my understanding of the distortion graphs (EDIT: speaker distortion). I believe its basically a comparison of signal in v’s measured output. Does this mean a sweep is performed and measured as per FR graph? Does the deviations from flat on a FR graph show up as...

Are they meant to sound this way? Like the measurements below, they are pretty dull on the high end. Do the measurements look like they're broken in any way? If they're not (both speakers measure similarly), what could the consideration be for such a sonic design? I've no idea what generation...

Speakers are usually able to accept quite high impulse power and measuring of speaker distortion by sine bursts would show if we are still in relatively linear region. The pain of sine burst distortion measurement is in length of the burst, which may not be long enough to get sufficient...
