Amplitude bumps in transducers imply predictable phase anomalies and time ringing.

Evidence

Resonances that occur within the normal operating ranges of transducers are minimum-phase phenomena, meaning that a bump in an amplitude response is sufficient evidence to predict that there will be a localized phase anomaly and ringing in the time domain. — Toole, Floyd E, Sound reproduction- the acoustics and…, 899
