There are two paths and these are not clear choices.
If one designs around some type of music, particular song or style, then one is on one path.
If one designs a loudspeaker to be maximally faithful, then one is on another.
The first path is fine if they are your speakers and are "tuned" for your music but this is a disaster for speakers that others will be using as their tastes are likely different than yours.
The other path is complicated by ones hearing which is an individual experience and irrevocably tied to the ear / brain system composing a single auditory experience base on two inputs.
For the latter path, what can be useful is a generation loss recording where the loudspeaker playing music is recorded with an instrumentation microphone and then evaluated with good headphones and this by passes the stereo image process. The difference is stunning when one hears the loudspeaker live and then the recording and often once one hears the "warts" as recorded, they often become just as audible listening live once one knows what they sound like.
More generations simply exaggerate the flaws with each generation and it is VERY rare to have a loudspeaker that is tolerable after just 3 generations. Here, the most faithful speaker will also reproduce the widest variety of music favorably for the audience of each AND if informally captured on an iphone or video, also sounds "different". We do this kind of testing at work on "large" loudspeakers because larger the system and distance, the greater the difficulty in being "faithful" If you have headphones on your computer, here is a video of a stadium sized speaker at 400 feet which demonstrates this.

AS for the scientific Psychoacoustics, this is not an easy area at all but a good deal is known in spite of that but this is an academic area and not strongly related to hifi sales. A co-worker has done a lot of work in this area and the link is to some recordings which use "how the ear works" to create the impression of space, movement and position. Doug is professor emeritus in acoustics, has designed many recording studios and listening halls and is in charge of education at the company.
