What to bring to speaker listening tests?

You might be able to correlate some measurements to perception but you can't replace perception.

I mean, you're correct about this, but what you said in post #17 is confused / confusing. "there are things about speakers that can't be measured..." But no, as you note, in most cases (i.e. speakers that fit on a klippel) we can measure every aspect of how they radiate sound into space with good accuracy.

You can't measure the perception of imaging / the illusion of space. Because this isn't a "thing about the speaker", it's a thing about the listener.

This effect of the speakers disappearing and all images coming from points in space rather than a clothesline stretched between the speakers is caused by a sufficient output to the rear and rear/sides which is in turn caused by the radiation pattern of the speakers. The simplest example I can give you with commercial speakers would be the open baffle, which has at least as much output to the rear as to the front

The perception you describe, practically a truncated pyramid, is achieved primarily through an excellent recording with the right balance of direct/reflected sound, speaker placement, the listening triangle relative to the room's walls, and acoustic treatment. An excellent polar pattern. If you measure everything, with patience and experimentation, what you call spatiality will eventually emerge!

Once you have obtained the truncated pyramid, it is only the beginning. Inside the truncated pyramid, you need to focus the individual sound images, starting from the central one, the first one you need to obtain, but that's another story.

Oh I agree you can’t measure things that aren’t in the signal(s) by measuring the signal(s).

I suppose there are some brainwaves and such that would offer a clue, but that’s out of scope. Besides, that sort of stuff isn’t limited to speakers.

ahofer, you won't get this for another couple of decades, but the sound field that is projected into the room is not caused by "signals" in the sound tracks, it is caused by the radiation pattern, speaker positioning, and direct to reflected ratio of speakers and room. Those factors are the essence of what we hear from all systems.
