There is no standard. The measurements are often more from the sales department than the engineering department. Just use as a rough guide.
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?
