@123toid I understand your point, I will have to play around with it some more and decided which route to go. Do you have anything you can say pertaining to my question above about the cone excursion plot in Winisd whether it is showing peak excursion under peak power for each frequency or is it just showing the excursion under the rms value at each frequency? It appears to show peak power from what I can find but would love to get confirmation.
