Audio Dynamics speakers were designed to reproduce music with ultimate accuracy.
\nOur speakers will pull you into the musical performance and breath new life into your music collection.<\/p>\n

This particular model has a rubber seal added from the tweeter pole to the cone so it keeps debris and water off of the voice coil. This makes this speaker extra rugged when mounted on motorcycles and other outdoor application.<\/p>\n
