Meeting Location: Technical University of Denmark, Lyngby, Denmark
This meeting was a cooperation between Technical University of Denmark(DTU, AES Denmark, Danish Acoustical Society (DAS). Finn Agerkvist hosted this event which showed that several companies and organisations during the previous years have gained significant insight into the mechanism causing distortion in loudspeakers. This brings hope for a less distorted future!
