I bought the 4.1 set and im trying to figure out the placement for them. I am concerned though. The placement of the 2 rear speakers are about 5 feet from a woodstove. I am concerned the heat may damage them? I am guessing the temps can get well over 100 in the area where the speakers are placed will they be ok? I guess if I had to maybe I could mount the on the ceiling as a last resort. Any help will greatly be appriciated thanks.
