My drums are set up in an unheated barn. I've played them in temps ranging from the 90's and all the way down into the upper 20s' (when I was too cheap to fire up the kerosene heaters). To my ear, I don't hear a whole lot of difference due to temperature regardless of whether it's in the 90's or the 20's. What does make the difference is the room acoustics. A snare that sounds excellent in my barn studio can sound like crap on a stick in the wrong room.
