ADAMThe German company ADAM Professional Audio, or Advanced Dynamic Audio Monitors, studio monitor speakers are designed around the Accelerating Ribbon Technology (ART) ribbon tweeters developed by Dr. Oskar Heil of Air Motion Transformer hi-fi speaker fame. Ribbon tweeters are capable of extended high-frequency response, but have traditionally been unable to output high sound pressure levels. ADAM ribbon tweeters feature neodymium magnets coupled with a lightweight diaphragm to solve this problem. Distortion, efficiency, dispersion or power handling of the ADAM ribbon tweeters all exceed the specifications of a 1-inch dome tweeter and deliver crystal clear sound combined with outstanding polar response and dispersion. The most recent X-ART ribbon tweeters and midranges show an eXtended frequency response and higher efficiency than their predecessors.
