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 a paper cone for its ability to deliver astonishing realism and detailed timbre across the harmonics.
Our 1000 series speakers will pull you into the musical performance and breath new life into your music collection.
