Thank you for the help!

Probably also the 20-20000 Hz rule had to be fulfilled

Hi,

I assume there´s an misunderstanding regarding the 96dB thing.
There was afair no specification for the efficiency of a speaker.
The 96dB figure related to the minimal maximum SPL the speaker should achieve.

Fortunatley it didn't. Otherwise veeeeeery few speakers of the 60ies and 70ies would have been able to fulfil the DIN norm for HiFi. Even today not many would pass either BTW.

I think we need to be a little more accurate here. There was the minimum SPL that had to be achieved in order to fulfil the norm as you mentioned. There was no minmal efficienciy value that had to be reached. I guess this is what you meant to say. But as already mentioned decent manufacturers published the "Betriebsleistung" of their speakers which is the power that is needed to reach a certain SPL value which made chosing amplifier/speaker pairings a Little easier.
