Another definition is the degree to which the output signal matches the input signal.

That doesn't take into account if the amplification is linear, only if it is equal at all frequencies.
when was the last time anyone posted up a 20 or 50hz squarewave ..
A square wave test isn't that useable on a speaker. Almost no speakers pass them very well because of phase changes over frequency. I would be impressed by a speaker that does do square waves well but there are many speakers that are not linear phase and yet superb reproducers and in some cases vice versa. I recall the Bowers and Wilkens DM6 from the mid 70s which was a fine speaker in its day and would pass square waves over much of its bandwidth but with the improvements of speakers in 40 years would no longer be at the top of the pyramid.

I posted your 1977 review of the DM6 to the Stereophile website review
archives this past week, Allen. (See link below.) I used these speakers
briefly back then and thought your review caught what the DM6 was about.

Thanks for link John, now I know who hahax is... Allen Edelstein.
sauarewave test suggested was for amplifiers not speakers , sorry i thought that was academic so did not specify .
