No, sitting around has not hurt them.
The response 2.5 is not a flat power or amplitude response speaker and the minimal crossover makes the 2.5 subject to a highly variable playback by not addressing the break up mode of the Carbon Fibre woofer as you have discovered. The harder you push the worse they get. Proacs are very incomplete speakers that require you to be very careful about placement and wall reflections.
It is the reason why so many people have to resort to low powered tube amplification to try to take the power response hump out of the midrange. I would look at the tremendous amount of
information on the DIY 2.5's to fix what is wrong with your 2.5's.
Proac completely under-utilized the potential of these drivers. Carefully picking from the DIY 2.5 info will substantially upgrade your speakers sound and make them more flexible.
