I don't agree, especially at this level zooming, without having off axis / directivities measurements you cannot choose a loudspeaker as for example on some designs you have some dips on axis that disappear off axis and are not significantly audible. In the other case FR problems can be easily EQed if the directivity is smooth but you cannot correct directivity problems. Also in my experience in upmost cases loudspeakers with a smooth directivity and some on-axis ripples sound better then the other way around, which is reflected also in the Harman score. Even LW is correlated better to perceived sound than on-axis measurements.
So coming back to the title of this thread "Can you choose a great speaker by its frequency response?" my answer is "No, if it is in that small tolerance band and if off-axis/directivites are not shown." Of course if the FR responses of some loudspeaker had a much higher tolerance band or were dropping off much earlier, the chances to be not preferred would be significant.
Speaker 1 - least variability, most bass extension.
Oh boy. … this is fun. What if I win ?
You can't choose a great speaker by an on-axis frequency plot no but if you have a complete CTA-2034 suite of measurements you most certainly can. All of the subjectively best sounding speakers are also backed up by good measurements.
Now you scaring meguess it mainly depends on how you feel about your decision when I reveal the speakers!
Now you are scaring me
Just kidding …
Whatever the outcome, it will be insightful.
I could imagine it is difficult to select the best speaker on FR only, but easier to weed out „bad“ speakers when trying to narrow down a list of speakers one is interested in to audition or even to buy.No disagreement, but that is not the spirit of the OP. Not all speakers have a full suite of measurements available and very few even have a simple published FR plot. Just to restate, these are all considered great (highly regarded) speakers btw.
Am giving you more data than you generally would have today in most cases. Less than 5 years ago, ASR did not measure speakers and you would have a lot fewer measured speakers.
So, still going to abstain?
When is the reveal?
