Vintage amplifier specifications

I've noticed when I read vintage amplifier specifications, and by vintage I mean 70's,80's maybe 90's, I do not see power output specified at 4 ohms. Did those older amplifiers not do well on 4 ohm speakers so leave that information out or was it not considered a a matter of interest to the buying public. Maybe something else?

There were speakers of this era that really needed amps capable of delivering into low impedances, such as Apogee, Infinity, Thiel, etc..

As an Acoustat 2+2 and Apogee owner… I agree.

Agree with others. Solid state high current survivors just don’t struggle with speaker loads. My old Crown offers only one set of outputs but lists power specs for 16, 8 and 4 ohm loads.

My trusty Sansui AU-999 still delivers the goods. Has specs for delivering 70 watts at 4 ohm load. Drives my DLKs perfectly.
