@Pim I agree with all you say apart from DSP. DSP is the only way to make a conventional box speaker time-coincident. In 1991-92 Celestion demonstrated that a "digital equalizer", the DLP600, could make a speaker with a 12dB/octave cross-over - the SL600si - time-coincident. Again it is John Atkinson of Stereophile who show this in measurements: https://www.stereophile.com/content/cele...nts-part-2
Today Kef, Dynaudio, Kii and others make speakers that correct the time domain (and any phase anomaly from the cross-over) with DSP.
