Frequency and time domain representations equivalently define linear loudspeaker behavior

Evidence

The combination of amplitude vs. frequency (frequency response) and phase vs. frequency (phase response) totally define the linear (amplitude independent) behavior of loudspeakers. The Fourier transform allows this information to be converted into the impulse response and, of course, the reverse can be done. So, there are two equivalent representations of the linear behavior of systems, one in the frequency domain (amplitude and phase) and the other in the time domain (impulse response). — Toole, Floyd E, Sound reproduction- the acoustics and…, 968
