Hi guys thanks for the reply,

I have to add the speakers where the oxidization occurred are located high up almost on the ceiling as per customer request. Also they are Mirage Omni Oasis omnipolars pointing down so this isn't a huge acoustic performance hit due to nature of the speaker design. At the other location where the 5T00UP was used where little oxidization occurred the speakers are at stand high. Perhaps the heat and moisture located at ceiling hight might be a factor?

PS I will post photos of the oxidization after 8 months use when I get a chance.
