I suppose you are right, but his point was asking about box speakers.
ALL of them distort the source material. How much is up to HIM to hear.
Period.
By the way, do you find it interesting that most "high-end" makers of box speakers have chosen a "tall" form factor ever since the late 1970's or so? I WONDER where they got THAT idea? I will have to ponder that one for a while, I guess...
