Celestion is acknowledged worldwide as one of the all-time greats of loudspeaker design. Ever since the Jazz Age, the name has been synonymous with the quest for immaculate sound reproduction.   Today, Celestion is still at the leading edge of audio design. Innovation is our way of life. Since the early 1980s, for example, Celestion engineers have used laser interferometry to design out undesirable cabinet colorations which otherwise distort the purity of recorded sound. Likewise, Celestion tweeters are unique in being designed with the aid of Finite Element Analysis to ensure greater consistency and a superior acoustic match.
