Minimum-phase loudspeaker resonances are correctable with parametric equalization.
Evidence
The fact that loudspeaker transducers are minimum-phase devices means that parametric equalization can be used to address resonances in them. Reducing the amplitude of a resonance peak reduces the audibility of the resonance and damps the time-domain ringing. In technical terms minimum-phase systems are “invertible”. — Toole, Floyd E, Sound reproduction- the acoustics and…, 510
