Since the tweeter will aim all frequencies straight ahead whose wavelength is smaller than the tweeter's diameter, I have wondered why you wouldn't have to aim any supertweeter directly (horizontally & vertically) at the corresponding ear to even receive the higher frequency sounds at all.
For example, 20 kKz is 0.678" in length, so shouldn't any supertweeter have to be smaller than a half inch in diameter to be picked up by the listener off-axis (seemingly would require the left supertweeter to be aimed precisely at the listener's left ear and the same for the right channel)? 30 KHz (0.452") would seemingly require laser-like focus of the supertweeter at the listener's ears.
And yet I routinely see images of systems with the supertweeter aimed off-axis and often above the listener's ears as well.
Please correct me if I am wrong. I would love to understand this concept better.
Best regards,
