Lower Q spreads resonances wider in frequency but shortens time-domain ringing

Evidence

High-Q resonances have a small footprint in the frequency domain (a narrow, sharpish spike in a frequency response) and a long buildup and decay in the time domain. As Q falls, the resonance gets wider in the frequency domain, and time-domain events happen more quickly. Eventually, the frequency response gets to be “flat”, there is no evidence of a resonance and the time-domain misbehavior disappears. — Toole, Floyd E, Sound reproduction- the acoustics and…, 494
