What Does Speaker Impedance Means?

(Last Updated On: May 13, 2020)

Speaker impedance is considered a confusing subject which many people don’t like to explore. If we talk about the basic understanding of speaker impedance, it’s not difficult to understand. The feature becomes useful when you want to connect multiple speakers to an amplifier. In this buying guide, we will give you proper knowledge about speaker impedance.

What Is Speaker Impedance?

Most of the audio writers explain watts, voltage and power using an example of flowing water through a pipe. Many people will visualize and relate to it easily. If you think of a speaker and consider it as a pipe, the signal of audio is the music which flows through the pipeline. Bigger pipes can handle a more significant flow of music while a smaller pipe will handle the lesser circulation. The speaker who has lower impedance acts like a big pipe where a high level of electrical signals will pass. The flow becomes easy when the impedance is more economical. There are many amplifiers in the market which deliver maximum power of 100-200 Watts at 8 ohm or 4 ohms. The lower speaker impedance means the signal or music can flow freely through each of the speakers. You have to understand that most of the amplifiers are created in such a way that they can’t handle 4-ohm speakers. If we consider the example of the pipe once again, you can consider getting a bigger tube. Bigger pipe means that it can carry a lot of water (audio) if you have a powerful pump (amplifier). No matter what kind of speaker you purchase to make sure that the receiver of the amplifier can handle it. Otherwise, it can cause damage and will cost you a lot of money. The receiver will shut down on its own, which will be a signal that 4 ohms or above are not a suitable choice.

Can Low Impedance Guarantee High Quality?

If you are using low ohms speakers and there is no proper equipment for it may cause harm to your music or video system. In this situation, you need an amplifier, but if the amp doesn’t support the speaker, it will be of no use. The impedance of the speaker keeps changing as the volume keeps increasing or coming down. The impedance which we see on most of the speakers is usually average. Many people also believe that the impendence of the speakers is dependent on the overall range of audio. For car audio, we typically get 4-ohms speakers, and it is suitable as the music system of a car will run on 12V. It depends on how the system is created. When a low voltage is given to the device, the speakers of your car’s audio system will be smoother. There are many receivers and amplifiers which have a switch on the backside. The switch can be used to change the settings of ohms which can match up with your device. Buying the speakers which can fit well for the device or system you are using becomes essential.
