Perception of 50Hz is a very idealised notion, which does not relate to the reality I speak of. A bass drum lights up the room, particularly modally, very differently depending on which direction it is pointing and where it is located. Furthermore a kick drum wave FRONT hitting the head and body, is clearly felt by the skin. If it coming from one side only, it is blatantly tactile.
Mike, I recommend you get a bass drum in a room and discover the disconnect between (mis) reading someone else's theory about sound, vs actually hearing and feeling it.
