Audio Dynamics speakers were designed to reproduce music with ultimate accuracy. We use perfectly blended wool pulp cones and high quality German silk dome tweeters to achieve the most natural, tonally accurate, dynamic, and detailed sound reproduction. Realistic texture to voices and instruments give you the feeling of listening to live music rather than listening to a speaker. Therefore, listening fatigue that usually settles in with other speakers is avoided. Our speakers will pull you into the musical performance and breath new life into your music collection. Our “Buy Manufacture Direct” program along with our dedicated Showroom Dealers, guarantees that our speakers are the best value of any on the market. We have compared our speakers to others costing three times as much.
