Audio Dynamics speakers were designed to reproduce music with ultimate accuracy. They spent countless listening hours examining the tonal qualities of many different cone materials; from glass fiber to Kevlar, to carbon fiber and more. Ultimately, they chose wool pulp for its ability to deliver astonishing realism and detailed timbre across the harmonics. They then added an acoustically-transparent chemical to help the soft parts resist moisture. They choose a titanium tweeter for its low distortion and high-performance characteristics. Their speakers will pull you into the musical performance and breath new life into your music collection.
