As I’ve said before, there is a way in which speaker measurements can be made easier to comprehend, which is by an adopting a target curve as your general criteria.
So if you just take the general type of response cited on this forum as indicative of a well designed loudspeaker with good sound, you’d be looking at essentially what some call the Harman Curve. It doesn’t take long to recognize the pattern there of the essentially flat on axis response with a gently sloping evenly spaced set of off access responses.
So you can say “ look for a measurement like this this sounds good.” And then one can also have their own experience of having greatly win down their selections, listening to loud speakers with essentially that curve, and understanding with that sounds like.
But where things get far more difficult is when you ask “ OK but what do all the other loudspeaker designs sound like?”
In that case, there are so many different speaker designs that measure so differently, you are being asked to look at a large variety of all sorts of different measurement aspects and somehow knowing just from the measurements exactly how any loudspeaker at all would sound. That takes a different level of understanding and direct experience correlating measurements to their Sonic consequences.
And then, what do you do if your interests extend beyond the relatively few available loudspeakers that have not spinorama-level measurements? Then it seems to be a “ try to hear them yourself” situation.
So on that level of knowing what all loudspeaker sounds like just from the measurements, not to put you on the spot, but I’m curious about what you would infer from this set of measurements.
If you were put into words what these measurements tell you in terms of the subjective effect, what would that speaker sound like?
I’d open up that question to anyone else here who would take a stab at it.
(I ask because I have quite a bit of experience, listening this loudspeaker):

(From stereophile)
Gosh, this is not not putting me on the spot.
I have never heard that speaker, and describing how it sounds from this isn't easy. Knowing how Stereophile frequency response measurements usually look, I would guess this is likely a lean both in the bass and upper bass / lower mids, so from that perspective not my kind of speaker. There's a pretty narrow peak/boost at the port tuning that may be audible on some tracks, which is not ideal. Beyond the bass I suspect it may sound tonally decent in-room, and also when moving around. Off-axis is not ultra smooth but not horrible either.
It's a bit uneven between 1-4khz, which is also not ideal, but it is hard to know how audible. Just looking at the response I would expect that it may sound a bit harsh on some tracks, and possibly lack a bit of bite on others. There's something happening off-axis at around 3khz too that may be adding energy to the room.
There's some significant resonances at 150-200hz, again hard to know how audible it will be in practice, but I suspect they might be perceived as coloration, again not necessarily on all material.
I am not going to pretend the step response tells me anything at all about how it sounds, because it doesn't.
Looking at the impedance curve there might be something going on at 2khz too, which is likely to shine through. All in all with a lean response and a number of resonances across the spectrum, I suspect this would not be my favorite speaker.
