Tweeter Design A tweeter is a small driver dedicated to high-frequency reproduction. There are several types all with their own attributes, good and bad and generally the technology involved will have a large baring on the overall price of the tweeter. Cone tweeters are the most common and economical, they have proven to be efficient and a cheep option for reasonable sound quality. Dome or "edge-driven" tweeters are the type found in most home speakers. They have excellent clarity and sound dispersion. Unlike a most tweeter types which move independently of the woofer, a whizzer is a small paper cone fixed to the woofer¿s center. both cones move along a common axis reducing the phasing that can occur between two separate cones when the cabinet is heard from different angles and distances. The result has a very natural-sound. Horn tweeters deliver low-distortion and superb high frequency sound.
