In all fairness, the diaphragm in a horn is not immune to breakup and the additional acoustic load may actually exacerbate the problem. Further, horns provide uneven loading at low frequencies where the horn is less than 1/4 size. This is linear, but still represents rapidly shifting phase. Throat distortion isn't an issue except at very high SPL, but it does introduce non-linear behavior. Magnetic non-linearities from the movement of the voice coil introduce non-linear behavior. All these things prevent a horn from operating with zero phase shift, same as a direct radiator. There is only the advantage of acoustic load, which is significant, but certainly not the only contributor to transient performance.
