Advanced Speaker Designs For The Hobbyist And Technican

Advanced Speaker Designs shows the electronics hobbyist and the experienced technician how to create high-quality speaker systems for the home, office, or auditorium. Every part of the system is covered in detail, from the driver and crossover network to the enclosure itself. You can build speaker systems from the parts lists and instructions provided, or you can actually learn to calculate design parameters, system responses, and component values with scientific calculators or PC software. You can also learn how to measure driver parameters and predict system responses for greater precision.

The definitive do-it-yourself book on creating & testing all kinds of speaker systems is updated for the computer age, covering the latest makes & models & featuring an innovative computer program to assist with speaker design. Previous editions of this compendium of simple-to-advanced projects have sold well, thanks to a large audience of electronics hobbyists & technicians, handy audiophiles, & libraries & technical schools. This version supplies step-by-step details on using the expanded computer program, which can be ordered at significant savings with an included coupon. It also includes new speaker tests, expanded information on crossover networks, techniques for designing double-chamber reflex enclosures, practical rather than theoretical dimension charts, & more.

Introduction to Loudspeaker Design is written for students, technicians, engineers and hobbyists 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 construction. A complete chapter is devoted to the subject of crossover design including design equations. The second edition adds a new chapter on simulation and analysis which includes design equations for closed and vented type speakers. The appendices contain technical references, design aids, glossaries 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 spanning both hardware and software. His WinSpeakerz, TrueRTA and DATS software applications are widely used throughout the audio industry as tools for simulating and measuring loudspeaker performance. Captain Murphy served as a space systems analyst for NORAD during his military career. Changes for the Second Edition: The second edition brings new material and polishes the first edition with many new or improved illustrations. Chapter 2 was expanded with the second half split into a new Chapter 3 titled "Speaker Response Functions." The discussion of Thiele-Small parameters has been expanded and now covers small-signal parameters vs. large-signal parameters as it explores the role of the test signal level in parameter measurement. The crossover design chapter has been expanded to include formulas for calculating component values for the most popular crossover types. Equations have been added for calculating impedance compensation and attenuation networks. The old Chapter 7 FAQ material was integrated into other chapters as appropriate. A new Chapter 8 titled "Loudspeaker Simulation" has been added and introduces loudspeaker equivalent circuit analysis with equations for calculating the magnitude and phase responses of closed and vented loudspeaker systems. Additional design equations are introduced and then examples are given for calculating the responses of a closed box and a vented box loudspeaker. Detailed design equation summaries are given for closed and vented boxes. Appendix C was added to provide a glossary of symbols and a glossary of terms. The box type charts were moved to Appendix D.

This volume seeks to lay the groundwork for readers who want to understand the general functions of loudspeaker enclosure systems and eventually experiment with their own designs. Written for design engineers and technicians, students, and intermediate-to-advanced acoustics enthusiasts, it presents a general theory of loudspeaker enclosure systems. Featuring illustrated and numerical examples, the book examines diverse developments in enclosure design, and studies the various types of enclosures as well as varying parameter values and performance optimisation. Topics examined include: the synthesis of vented systems; infinite-baffle and closed-box systems; electro-acoustical relations; and reflex response relationships.
