What Is Speaker Impedance and How Does It Work? - Audiosolace
https://audiosolace.com/speaker-impedance-explained/
In technical terms, speaker impedance (and to some degree, headphones impedance) refers to the load an audio peripheral sends to a connected amplifier when in use. Note that when we are using any audio peripherals, the audio signals being sent from the audio source to the peripheral are electrical currents themselves (see “audio signal”).
Impedance – How to Optimally Connect Speakers to an …

For an optimal power transfer the amplifier’s impedance should be equal to the total impedance of the speaker elements. If the speaker impedance is too low, the amp will have to work too hard (i.e. deliver too large current) and possibly overheat. If the speaker impedance is too high, the amp will be unable to deliver full power, but this will not be dangerous to the …

Yes, it is perfectly possible and the speakers will produce music quite normally. In practice, the amplifier does not detect the impedance of the speaker: it works, a point that’s all. If the impedance of the speakers is 4 Ohms at 1 kHz, it may be higher in the frequency band between 40 and 100 Hz, for example, where the amplifier is most stressed.

A speaker’s nominal impedance is usually 2, 4, 8, or 16 ohms. Written on the back panel of the amplifier or in its technical specifications, you’ll find the impedance rating of your amplifier. The impedance rating of an amplifier usually ranges between 2 ohms and 16 ohms.
Amplifier Output Impedance (Damping Factor) and …

This is an update to the earlier posts describing how amplifier output impedance (or damping factor) might affect the sound you hear from your speakers. First note damping factor, DF, is the load impedance divided by the amplifier’s output impedance: DF = Zload / Zamp.

Generally, amplifiers need to have connected speakers that have an impedance of at least 4 Ohm (this is a reference value, which depends on each amp). The range of impedances allowed is usually indicated on the back, where the cables connecting the amplifier and loudspeaker are located.
Audio Amplifier Circuit

speakers have a low impedance, typically 8-Ohm. Even for a low-power 0.5W audio amplifier, PIR 2 /2 requires that the amplifier must be able to source a peak AC current of around 350 mA with an 8-Ohm load. This is a lot more than a typical op-amp is designed to provide. For example, the LM358 and LF353 (two op-amps used in this lab) can source

Solid state amplifiers can power any speaker of rated impedance or above. Impedance is an opposition to the flow of electrons. As your impedance falls, more electrons (current) flow. Increased current causes heating beyond what the output semiconductors are designed to handle. Raising impedance lowers the current so involves no risk.
