 Introduction to Loudspeaker Design




(comissions earned)

Introduction to Loudspeaker Design, Second Edition is written for hobbyists, students, technicians and engineers seeking an overview of the technology of loudspeakers. Starting with a brief history of audio developments the book begins by introducing the concepts of frequency, pitch and loudness and proceeds to develop the idea of a loudspeaker as a system.

The book covers such topics as loudspeaker design tradeoffs, spatial loading, diffraction loss, cavity effect and enclosure design. A complete chapter is devoted to the subject of crossover design. The appendices contain technical references, design aids and a chart depicting 18 different loudspeaker enclosure types.

The author is a physicist/audio design engineer with over 35 years experience in the research and development of audio products. His DATS, WinSpeakerz and TrueRTA applications are widely used throughout the audio industry for simulating and testing loudspeakers.

The 2nd edition in paperback is just $24.95.
