Cameleon Queen, Princess, and Voice

I recently came into a set of Cameleon Floating speakers. The set consists of a pair of Cameleon Queen Tower Speakers, a pair of Cameleon Princess Tower Speakers, and a Cameleon Voice Center Channel Speaker. These seem to be pretty darn rare. I wanted to know what people thought of these as far as quality and used value are concerned. Thanks in advance, Evan
