Procella P815,P6 and V21 measurement from Trinnov training

[Smythson]

Here is the in-room measurement from Trinnov itself during ISE 2020 , The measurement below is the P6 and V21.

Here is P815 with V21.

Warning: The showroom has room acoustics treated

What do you guys think? Maybe that's why there is no measurement online for procella. lol

I think in-room measurements are an incomprehensibly poor method of judging subwoofer performance
