There is only one definition of acoustic center. It is in D`Appolitos book.

It is the delay that causes the excess group delay to be flat.

Better stated as the point along the driver axis relative to which the phase reduces to minimum phase. But in truth it is pretty academic and there is no need to try to find the AC of a driver.

Other ways to say it: The delay for which the measured phase equals the Hilbert transform phase, or the delay for which the excess phase is zero.
