Your 1st photo confused me because it shows a dark black area below the light brown board and I wondered whether that was part of the mod or perhaps some kind of fixing tape.
By the way my P3s don't have nearly as much foam bulging in to the cavity as yours so that might explain why I am not unhappy with the sound. I will try to find some suitable board though. Perhaps this year someone will send me a Christmas card
