Home Speaker Asylum

General speaker questions for audio and home theater.

Re: Does a loudspeaker's time coherence matter ?

Note that the speakers on this list - Dunlavy, Green Mountain, Vandersteen, Meadowlark, Theil - have extremely low diffraction cabinetry.

Recent research suggests that diffraction is quite audible, though not because of its (minimal) effect on the frequency response curve. Diffraction is audible because it arrives later in time than the original signal, so its presence isn't obscured by the auditory system's "masking" effect.

I think that time and phase coherence is beneficial, but I'm not convinced that it's necessarily the most beneficial thing going on with these designs. I think they do enough other things well that they'd be excellent speakers even with higher order crossovers.
