Low output impedance vs high output impedance of an amplifier
https://electronics.stackexchange.com/questions/130414/low-output-impedance-vs-high-output-impedance-of-an-amplifier
The music produced by the AMP is a waveform. And the objective is to produce that waveform on the speaker, one time, and not have any echo (of the waveform). A low-output-impedance amplifier assures there is a low resistance to GROUND (to attenuate any residual sound coming from the speaker when it reflects (the music waveform) into the amplifier).
Output impedance – PS Audio

Let’s say your loudspeaker is an 8 Ohm speaker whose impedance dips as low as 3 Ohms at its lowest point (speakers don’t have flat impedance). That means the output impedance of your power amplifier should be at least 0.3 Ohms and probably better at 0.03 Ohms to really have very little affect. Tubes generally have higher output impedance than solid state products. …
What is Impedance in Audio? Input and Output …

What this is telling you is the resistance that the speaker presents to the amplifier. A lower speaker impedance means that there will be more power flowing from the amplifier. In contrast, a higher impedance speaker will have less power flowing from the amplifier.
High Input Impedance and Low Output Impedance in Op …

The short summary: input impedance is "high" (ideally infinite), output impedance is "low" (ideally zero). Op Amp Impedance Matching. Ⅱ High Input Impedance and Low Output Impedance Effect. The high impedance ensures that it draws very little current. It is the amplifier's task to convert a low energy, voltage-driven signal into a higher-voltage output signal. Low …
Understanding Impedance - Sound on Sound
https://www.soundonsound.com/techniques/understanding-impedance
In general, amplifiers are designed to have an extremely low output impedance (usually fractions of Ohms) so that the loudspeaker impedance is significantly higher. However, the impedance of the connecting cable can also have an audible effect on the sound quality.

In this case, the voice coil of that speaker has a very low impedance, not more than 20 ohms only Voltage from the voice coil is very low, only less than 0.01V. And older AM radios also use low impedance speakers, too. Recommended: Simple Transistor intercom project. We can increase impedance by using matching transformers.

There is no negatives to having a headphone amplifier with a low output impedance (like 1-Ohm or less). A headphone amplifier with an output impedance of 1-Ohm is fine for driving a 600-Ohm headphones. That same headphone amplifier (1-Ohm output impedance) would also be fine for headphones with only a 10-Ohm impedance.

You can put the speakers in series. 8 + 6 = 14 ohms. Performance may suffer a bit, as the speakers will not directly “see” the low output impedance of the amplifier, affecting the damping factor and possible crossover accuracy. This is a transistor amp. Tube amps with their output transformers behave differently.
