Winisd RMS or peak data?

[Scarface1]

Hi, it seems that winisd ( beta ) calculate RMS values like Input power, SPL , amplifier apparent load power and Voltage BUT is this also for Xmax? Xmax at peak is higher of course and i read earlier that it predicts peak Xmax but i can't remember so i want to know for sure, thanks!!

Everything in WinISD is RMS. Of course, there really is no such thing as RMS power, but that's a different discussion.

Thanks, how about the Xmax? When i calculate with speaker box lite i get +3 db because it shows peak power but i get the same Xmax as Winisd. So this tells me that winisd predict Xmax at peak power.

I have my answer, Xmax is at peak vallue!
