AB  - Most single-cone dynamic loudspeaker drivers are, very accurately, minimum-phase devices. This means that their amplitude and phase responses are accurately related by the Hilbert transform and that, therefore, their minimum-phase phase responses can be obtained by computation, from amplitude response measurements, alone. The problem of making this computation is analyzed and a new algorithm, implemented as a BASIC language program listing, is given. The method can be applied to the precision location of driver acoustic centers, using a precision FFT Analyzer. It can also be applied to obtain accurate phase response information and to the location of driver acoustic centers, for purposes of computer-aided crossover design, using only amplitude measurements.
