A point is by definition a dimensionless or infinitely small location in space. Dimensionless or infinitely small objects cannot possibly produce sound. (Some will no doubt now go chasing after these speakers with zero room interactions.) I mention this only to illustrate how easy it is to go off the rails talking tech. Jargon is a creature unto its own.
I never once in my life went to hear a point source, or a dipole, or even a horn, folded or otherwise. Never went to audition isobaric, line array, or any other speaker design approach. All I ever went to audition was speakers. Then evaluate whatever I hear in light of the room, music, associated equipment, and yes maybe even speaker design. Maybe. Sometimes.
In other words I never put the cart before the horse.
