This changing "reactive" load causes the amp output level to change with frequency and changes in speakerimpedance (a dynamic thing that changes as the speakers are driven harder).
But continuously press the speaker, if the moment strong current passed impedance can still regular work, quare will like bad.
但不断按喇叭时，若瞬间强电流通过阻抗依然能正常工作，所以会时好时坏。

Sometimes a lot - for instance, you might see an impedance result of anywhere from one to as much as 50 ohms from a particular speaker design within it's normal operating frequency range.
