Loudspeakers at high power and low frequencies become highly nonlinear.

Evidence

Examples of systems where linearity is of importance are audio recording and reproduction equipment. Amplifiers can be designed to have low non-linear distortion, but, for example, loudspeakers at relatively high power levels and at low frequencies can be highly non-linear. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 353
