Speaker impedance is a measure of the resistance {that a} speaker presents to {an electrical} sign. It’s sometimes 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 will not be fixed, however varies with frequency. The impedance of a speaker is usually highest at its resonant frequency, which is the frequency at which the speaker cone resonates most simply. The impedance of a speaker can be affected by the temperature of the speaker and the quantity of energy that’s being utilized to it.
