The real question -- and I'm actually surprised nobody has brought this up -- is how the increase in average global temperature (regardless of its cause) will affect the sound coming from our speakers??
I think I've already started to experience some of what is to come... at 95 deg F and 95% RH the bass seems to hit a little harder, you know, with the higher air density, and all
funny, but i always thought and felt that higher air temps mean lower air density...
open the fridge door, and the cold air drops down to your feet; start the heater, and the warm air goes up towards the ceiling...
