Wharfedale Opus Repair / Replacement issue

So a few years ago I purchased a pair of Wharfedale Opus 2 tower speakers. They were a pretry penny, but fantastic speakers. Recently the tweeters have gone out, and wharfedale is of no help to me what-so-ever. Are their people out there who can do repairs, or am I SOL on my lovely speakers? Any guidance would be muuuuch appreciated :(
