Howdy sorry but surprised with the examining of the PIR in this thread in what appears to be an attempt to hear the speakers.
It is my understanding that this is not what the PIR is.
I believe it is fairly clear in Toole's book. You can not hear the speaker from looking at the PIR - that PIR is novel and only a modestly useful component of the whole data package.
It is not granular and it is not really what is heard in room nor capable of communication what myriad of values of sound energy are hitting the ear/brain system….I see regular use of PIR analysis at a level which seems to me beyond the scope of the predictions intended value as a tool.
You’re not the only one!! Many seem unaware of Dr. Olive “curve drawing” study, in which trained listeners perception of speaker FR tracked the anechoic listening axis.
I’m honestly surprised by the gushing over this speaker based on the measurements. Specifically, the midrange/tweeter dispersion disruption shown in the horizontal polar map, which usually correlated with upper mid colorations in my experience. Maybe it’s worth auditioning - always good to challenge one’s preconceptions.
