I don’t fully grasp the meaning of “minimum -phase” behavior of rooms and why transducers are intrinsic minimum-phase devices. All in the light of the ability of room EQ to improve the room response.
Are there any good articles or books on this topic?
Most phenomena in nature are minimum phase.

Standard resonances, both mechanical/acoustic and electrical, are all minimum phase.

Hence correction should also use minimum phase, which has a corollary of a symmetric relationship to frequency response.

In a fully minimum phase environment, correcting f/r using minimum phase filters will also correct phase, and vice versa.

Hence for most things audio, it is best to stick to minimum phase filters.

You can have for example mechanical or electrical systems that are NMP, but to put it very non-stringent, they typically take more effort to make.
