RE: JBL 2441Throat Diameter

AS long as the step in size for increasing area is less than about 1/4 wavelength at the highest frequency of concern, the transition has no significant / measurable impact.
20KHz has a wl of about 5/8 inch fwiw.
Going down in size can act like a low pass or worse depending on how large it is.
