Well I'm not going to give my 2 cents on whether on not light or heat darkens the wood but HDBR worked for Klipsch for a long long time and tbh his initials are probably on your Klipsch speakers as he did A LOT of them. based on his experience in the Klipsch business for over easily 20+ years i would believe whatever he says over some articles no offense, he has more experience with Klipsch speakers than probably 99% of people on the Klipsch forums. I don't know hdbr personally but i know he is very knowledgeable on everything Klipsch and I would believe him on the affects of heat/light on the speakers over any article but that's just me I guess.
