Area calculates out to just over a 2-1/8″ round port. The Port velocity is at the 120 W max it might hit, which puts it at 14 m/s. Sitting at 60 W rms, it’s down at 10 m/s.The excursion is what is bothering me. It should be moving a lot more. Granted, they only have an XMAX of 3.5 mm, but as low as they show, and at the 120 W setting? I can zip the WDR and the WPR if you need to see them, to see if I messed up somewhere.
