Which Impedance? Nominal Minimum / Maximum Average

By Pat Brown

This article addresses three dominant reasons for measuring the impedance of a loudspeaker.

The impedance of a loudspeaker characterizes the opposition that it presents to current flowing from the amplifier. The impedance is both complex and frequency-dependent. … Read more
