Hi guys, long time reader, first time poster. Im about to purchase a pair of CLX's used ( a little over a year old ) and was curious on a few things. First, i live in the desert ( palm springs area) and was curious on how long the average panel last. The reason i ask is because i have seen how expensive they are to replace and was hoping for at least 5 to 6 years before i have to replace them, the area i live in is very dry but i keep my house at around 75 degrees F. Second, this is my first electrostatic loudspeaker and is there anything i should know in terms of maintenance. Thanks again
