Subjective vs. objective? Or subjective and objective?

It has basically been raining for two weeks where I live with another week of daily rain in the offing. The humidity is quite high and the mold count quite high. Think that doesn't have an effect on the sound of mdf speakers especially the bass vented cabinets of my Cornwall 4's? It does - not extreme but definitely audible. An option would be to brush on a true high solids varnish to the inside cabinet walls ideally at a time of low humidity. Problem is it would probably alter the "tuning" of the cabinet and not be easily reversible. I long ago decided that such measures are not worth the risk. In the general scheme of things messing about with tolerances at this level just feels like too much of a mine field, and it is enchanting to be riding a horse that has its own slightly variable personality. I had a horse like that when I was a teenager. His name was "Blackie" - solid black with ferocious, foamy sweat in the hot months. You never quite knew what his mood would be from one day to the next, but he was magnificent.
