W10: LOUDSPEAKER LINE ARRAYS – PART 1 (Theory & History, Tutorial)
Chair: Jim Brown, Audio Systems Group, Inc
Wolfgang Ahnert, ADA/Acoustic Design Ahnert
Stefan Feistel,Software Design Ahnert
Kurt Graffy, Arup Acoustics
David Gunness, Eastern Acoustic Works
Mike Klasco, Menlo Scientific
Don Keele, Harman Motive

This tutorial workshop is targeted at working sound reinforcement professionals. The session includes development of basic concepts underlying line arrays, both simple and complex, an historical survey of commercial line array products, and a variety of line array design techniques. Methods of predicting line array performance are described, both at the conceptual and practical level. This session is a highly useful precursor to afternoon session W12 (Loudspeaker Line Arrays, Part 2 - Practice & Applications).
