Speaker impedance is a measure of the resistance of a speaker to the movement {of electrical} present. It’s measured in ohms (), and it is a crucial issue to contemplate when matching audio system to amplifiers. If the impedance of a speaker is just too excessive, the amplifier won’t be able to supply sufficient energy to drive the speaker, and the sound shall be weak and distorted. If the impedance of a speaker is just too low, the amplifier could also be broken.
There are a couple of alternative ways to verify the impedance of a speaker. A method is to make use of a multimeter. Set the multimeter to the ohms setting, after which join the probes to the speaker terminals. The multimeter will show the impedance of the speaker in ohms.
