PS343 – 4000 Series 3″ point-source

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