That's why in room measurements are meaningless to a manufacturer unless every room was like the one they were measured in.
Except that is where we all end up listening to their products.
Default standard for speaker "sensitivity" measurement listings? Anechoic? In-room? Other?
I’m researching speakers which will play nice with tube amps.
I recognize that a number of factors are at play, not least sensitivity and impedance. Too low an impedance dip and/or too many wild swings in the graph and they tube amps may find driving the speakers a challenge.
So...some companies list BOTH in-room and anechoic sensitivity for speakers. Others just say "sensitivity."
QUESTION: When a company ONLY lists “sensitivity” is it understood to mean in-room or anechoic? Or something else? Or is there no standard one can assume?
