Output impedance – PS Audio
https://www.psaudio.com/pauls-posts/output-impedance/
Output impedance refers to a device’s ability to deliver unrestricted current or power when passing a musical signal – it measures the amount of restriction or hold back of that signal. It is important to understand output impedance only as it is relative to the input impedance of whatever the amp is driving.
Amplifier Output Impedance: The Amplifier - Loudspeaker ...

Using a loudspeaker that has a 4-ohm minimum and a 70-ohm maximum and the same 5V 2-ohm output impedance amplifier from before: Vmin = 3.33V and Vmax = 4.86V. This is a 46% change in the voltage across the speaker due to its changing impedance! 3. …
Amplifier Output Impedance – It Matters - Samma3a Tech

When the amp outputs a quick electrical signal (impulse) to the headphones, what follows is the driver moving accordingly to the impulse, and then there are a few little “bounces” of the driver after that. This is called ringing. The less ringing you have, the less those unintended driver movements can interfere with the next impulse.
What is Impedance in Audio? Input and Output …
https://virtuosocentral.com/what-is-impedance-in-audio/
In audio devices, impedance is the measure of the resistance of a circuit to alternating current (audio signal). It’s measured in Ohms. The “Z” symbol represents impedance. All audio equipment that receives an input and has an output will have impedance measurements, namely input, and output impedances. More on that later.

Typically, most microphones therefore have an output impedance of 150-200Ω, and most preamplifier inputs offer an input impedance of between 1.5kΩ and 3kΩ — on the limit of the 'ten times higher' rule of thumb I mentioned earlier.
Impedance Matching of Audio Components

The output impedance is low, and the output voltage and power are controlled dynamically. The implications of the simplified model for resistive amplifier outputs and speakers may nevertheless be instructive as a reference. For example, assume that the maximum distortion-free voltage from the amplifier is 40 volts:

put a 1kHz tone on it, measure the output voltage without a load, then apply a low R load (say 10 Ohm) and measure the voltage again. The ratio between the voltage without a load - loaded voltage and the voltage across the load is the same ratio as the known load and output R.
How important is impedance matching in audio applications ...
https://electronics.stackexchange.com/questions/6846/how-important-is-impedance-matching-in-audio-applications
Impedance matching is not used in modern audio electronics. A mic output might be around 600 Ω, while mic preamp inputs are 1 kΩ or more. A line output will be something like 100 Ω, while a line input is more like 10 kΩ. A loudspeaker amplifier will be less than 0.5 Ω, while loudspeakers are more like 4 Ω.
