Nominal Impedance - KEF
https://us.kef.com/blog/nominal-impedance
There are two specifications for Impedance: Nominal which is more or less an average value, and minimum, which is a critical value to know when matching loudspeakers to amplifiers. Typically, the lower the frequency the lower the applied impedance the loudspeaker presents to the amplifier.
What is nominal impedance speakers?

Since music has a lot of simultaneous frequencies, what you end up with is something called “ nominal ” impedance. That's more or less the lowest amount the speaker will dip down to in resistance to the load applied at any given frequency within its operating range. Is 4 or 8 ohms better? A lower impedance speaker will accept more power.
What Speaker Impedance Means and Why It Matters

Impedance of Car Speakers . In car audio, 4-ohm speakers are the norm. That's because car audio systems run on 12 volts DC instead of a 120 volts AC. A 4-ohm impedance allows car audio speakers to pull more power from a low-voltage car audio amp. Car audio amps are designed for use with low-impedance speakers. So crank it up and enjoy.

In electrical engineering or audio, the nominal impedance of an input or output is the equivalent impedance of all of the output or input circuitry of a device lumped into one (imaginary) component. An impedance is a combination of resistance, capacitance, and …

The nominal impedance of an enclosure is that measured at 1 kHz unless otherwise indicated. The low impedance is the lowest value of the impedance curve, measured from low to high, from 20 Hz to 20 kHz. Some manufacturers indicate this low impedance (Focal systematically), even specify that their speaker has an impedance of 4-8 Ohms, a low …
Defining nominal impedance - High-End Audio Discussion Forum
https://forum.audiogon.com/discussions/defining-nominal-impedance
Nominal impedance of the speaker is defined as its design intended impedance i.e. the designer intended it to be 8 Ohms or 6 Ohms or 4 Ohms. i do see where you got the info that nominal impedance of a speaker is the lowest impedance after resonance....

Most readers will be aware that loudspeakers are quoted with a nominal impedance of usually four, 8, 15 or 16Ω. The last tends to be used with vintage valve amplifiers, the first with automotive and battery-powered systems. Loudspeakers are very complex things, and those with passive crossovers are often challenging for the amplifier(s) to drive.

The nominal impedance means nothing. You really need to know the impedance curve of a speaker. You could say the nominal impedance of a speaker like the one above is 8 ohms. However where the power is it is four ohms or less. The minimum impedance is about 3.5 ohms in the audio range.
