Radian upgrade for Zu Omen, 475be vs 850?

Hi all,

Been playing around with the thought of replacing the stock Emminence 1001 tweeter in my Omen Mkii’s.

I know that Zu uses the Radian 850 in their top range of speakers. This however is a 3in diameter diaphragm in a 2in nozzle, and should exhibit significant distortion above 10k Hz..

On paper the 475be should be much better above 10k, plus no new tweeter lens needed or any woodwork....

opinions anyone??
