Audio Dynamics speakers were designed to reproduce music with ultimate accuracy.


We’ve spent countless listening hours examining the tonal qualities of many different cone materials; from glass fiber, to Kevlar, to carbon fiber and more. Ultimately, we chose wool pulp for its ability to deliver astonishing realism and detailed timbre across the harmonics. We then added an acoustically-transparent chemical to help the soft parts resist moisture. We’ve gone to similar lengths in developing our tweeter components which use the highest grade transparent silk domes and powerful Neodymium motors to produce clear and effortless highs.


Our speakers will pull you into the musical performance and breath new life into your music collection.
