I have a pair of Kef Q90 speakers that I love and which have had very little use. I want to set up a home theater, but my local Kef dealers can't seem to provide me with advice on compatible speakers for the center channel, the subwoofer or surround speakers. My local audio dealers say Kef's are very difficult to match and that I'll have to get a whole new set of speakers. Does anyone out there have any experience in matching speakers like mine with others to make a home theater setup?
