Speaker Efficiency

Oh it will work. Almost any pairing will “work” and make sound. It might even work well enough for some in some cases. But the pairing will never bring out the best in either component.

Exactly!

Typo, the Electa Amator is 4 ohms at 88db

That means the speaker is getting two watts not one watt. I.e. Sensitivity @ one watt @ one meter @ eight Ohms =88 dB SPL @ four Ohms= two watts for 88 dB SPL @ one meter. In other words, your speakers are getting two watts from the amp not one to get 88 dB SPL @ one meter. Also, any amplifier driving lower impedances = higher distortion.😎

I agree!

Then why even make speakers in the 80db range if higher impedance is better?

One reason a four Ohm speaker will play louder then an eight Ohm speaker. See my post above. 😎

The video below explains impedance and the differences between efficiency and sensitivity.

Speaker efficiency is sensitivity

Not really! See article below page one sec C:
