2K is quite high for a 15", and it is likely that it does not behave like a piston source so high up.
But now it looks like they are going to measure it, so then you will find out.

I don't have any knowledge on this app, but I assume it presents vibration level in the frequency domain, similar to what REW does in the RTA.
