This is because as the impedance is lowered, the electrical current increases and the stereo has to do more work. It’s important that you pay attention and don’t exceed the minimum speaker impedance rating. Stereo and amplifier minimum impedance ratingsĪll amplifiers of any type – where it’s a car stereo amplifier, home stereo receiver, home theater amplifier, and so on, have a minimum Ohms (impedance) rating.

The good news is that you don’t have to worry too much about the details – it doesn’t matter for basic speaker use, and long as you understand the basic rules you’ll be fine! 2. Speaker impedance is just a more advanced way of finding the total resistance, and by tradition is measured in units called “Ohms.” The word used to describe this is called impedance. Because of this, there’s some extra math needed to figure out the total resistance. Loops of wire have a property called inductance which affects a speaker’s resistance value depending on the frequency (sound range) being played.Īs they have electrical properties that include inductance and capacitance, their “total resistance” can actually change with the music slightly. Speakers contain a long wound loop of wire called a voice coil. A voice coil is a coil of wire that, when placed inside a magnetic field, makes the speaker move and produce sound when driven by an amplifier. The resistance value comes from a long coil of wire inside each speaker called a voice coil.

The difference is how they behave when music is present when they’re connected to a musical amplifier of some sort. Speakers, much like other electromechanical devices, all have an electrical resistance to the flow of electrical current, much like a standard resistor, a light bulb, or many common items you’re familiar with.
