He hit the nail on the head, saying a properly built constant directivity cornerhorn has no reflections.
But I must admit, there are not many loudspeaker models that do the trick. All sound sources must be acoustically close to the corner or they must be directional. Just placing a typical loudspeaker in the corner won't do because it isn't close enough acoustically through the passband. If done wrong, it's most noticeable in the midrange.
