Speaker impedance is a measure of the resistance {that a} speaker presents to {an electrical} sign. It’s usually measured in ohms (). The impedance of a speaker is vital as a result of it impacts the quantity of energy that the speaker can deal with and the sound high quality that it produces.
The impedance of a speaker isn’t fixed, however varies with frequency. The impedance of a speaker is often highest at its resonant frequency, which is the frequency at which the speaker cone resonates most simply. The impedance of a speaker will also be affected by the temperature of the speaker and the quantity of energy that’s being utilized to it.
