and for speakers ?
The problem is that audio electronics cope only with one dimension (that is amplitude as a function of time) which in the last decades is easy to make inaudibly perfectly linear and with inaudible distortions but loudspeakers output in a 3-dimensional space and even if you would manage to make their output very linear and low distorted in one direction (which is already very hard) you never have the same exact output in other directions, as all different driver, baffle and crossover configurations give different radiation patterns.Does this apply as well for speakers, just like an amp have to reinforce a signal without adding or distracting something,
is it fair to say a speaker may as well not ad or distract something of the signal.
there fore the best measured speaker is the best speaker?
Not necessarily. The score is based on average listener preference. This means that more listeners will like a higher scoring speaker. It does not mean that every listener will like a higher scoring speaker.
The preference score is a perfect tool for commercial manufacturers who want to sell as many speakers as possible. It is not perfect (though helpful) for the individual buyer.
One key "secret sauce" that renders frequency response as woefully inadequate in determining the sound is driver materials.In my experience speakers that measures better also sounds better, which is not surprising given the research. The main factor for sound quality in speakers relates to frequency response both on and off-axis.
My experience is that speakers with equal frequency response will sound extremely similar given similar dispersion, so I've yet to discover a magic sauce that renders frequency response (including dispersion) insufficient to explain most of the perceived differences.

With identical frequency responses different speaker system using woofers (for example) made of paper, aluminum, ceramic, carbon fiber, poly, bamboo etc. will all have significantly different sound characteristics. Same thing for midrange drivers, tweeters and even subwoofers.
Different compounds, coatings and material thicknesses will also affect pitch, timbre and tonal accuracy in addition to driver base material.

This actually brings up another question I have meant to ask for a long time: a lot of people describes the 'speed' of the drivers, usually by people whose musical preference is mainly rock / metal / electronica.
Harbeth speakers are often criticised for been too 'gentle' and 'civilised', pipes and slippers etc etc, i.e. they are not 'fast. Personally I haven't had an experience where I play a song and think, hmmm this sounds slow.
How do you quantify this characteristic in measurements? How do you measure the start / stop time of a driver, if that's even possible?

With identical frequency responses and distortions lower than the perception limits drivers from different materials actually sound the same but only if you "switch off" their different radiation pattern, i.e. listening to them in free field conditions
The idea that all compromises are equal because they're compromises is sophism and nothing else.All speakers are inevitably very imperfect, so the analogy with small or non-existent differences between electronics is quite pointless. Of course, every speaker designer tries to push the envelope, but they all have to accept compromises and one designer's best compromise may not be another's, let alone to your liking.
