This discussion has re-invigorated my interest in the CRS+'s and so I just ordered a pair of replacement tweeters from Polk. They are supposed to be a improvement over the original drivers and so might be something to keep in mind if you do buy the speakers and might also be an argument for a lower price. There is also small fuse type device in the tweeter circuit on the crossover's that might also warrant replacement as I am told they sometimes cut out intermitantly when they get old and those are also available, and you get a nice discount on everything if you are a Polk Club (forum) member.
Oh, and be careful getting rid of those "decorations".
