I have a pair of Klipsch Heresey circa 1977, That are in great shape. I refinished them about 5 years ago, but otherwise have done nothing else to them. They sound as good as the day I bought them used in 1977. My question is do I run them till they die or is there any type of maintainence I shold perform on these. Will the woofers eventually dry out? Thanks Walter in Connecticut
