Query: Disappointed

I have previously had Cerwin Vegas and was very pleased. However after trying these CLS-10's I was totally disappointed. The highs were tingy and NO midrange was evident. No music other than a rumble came from the lower speakers. I determined that this had to be a defect in both speakers and returned them. Five stars for Amazon customer support!Ordered a pair of Bose 301's and they are WONDERFUL!
