Design and build customized, professional-quality speakers. From drivers to crossovers and custom enclosures, the possibilities for designing speakers that will provide the best possible performance are endless. Great Sound Stereo Speakers Manual, Second Edition, by David Weems and G.R. Koonce, eliminates much of the guesswork--not to mention the ripping out of parts and trying of alternative values--associated with proper design. More than a normal revision, this edition is virtually a new book, with a solution to an old problem, crossover design. This reader-friendly guide puts equipment-enhancing, computer-aided design techniques at your disposal. You get six complete projects, with lucid illustrated instructions for modifying and testing designs, along with 24 proposed projects. The CD-ROM packaged with the book gives you system design software, crossover network design applications, and files for all project drivers, allowing you to alter a project to fit a different physical arrangement of the drivers, explore driver substitution, perform driver tests, simulate box and network design, or customize the included projects.
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.

Designing Your Life
Author: Bill Burnett, Dave Evans
#1 New York Times Bestseller At last, a book that shows you how to build—design—a life you can thrive in, at any age or stage Designers create worlds and solve problems using design thinking. Look around your office or home—at the tablet or smartphone you may be holding or the chair you are sitting in. Everything in our lives was designed by someone. And every design starts with a problem that a designer or team of designers seeks to solve. In this book, Bill Burnett and Dave Evans show us how design thinking can help us create a life that is both meaningful and fulfilling, regardless of who or where we are, what we do or have done for a living, or how young or old we are. The same design thinking responsible for amazing technology, products, and spaces can be used to design and build your career and your life, a life of fulfillment and joy, constantly creative and productive, one that always holds the possibility of surprise. "Designing Your Life walks readers through the process of building a satisfying, meaningful life by approaching the challenge the way a designer would. Experimentation. Wayfinding. Prototyping. Constant iteration. You should read the book. Everyone else will." —Daniel Pink, bestselling author of Drive “This [is] the career book of the next decade and . . . the go-to book that is read as a rite of passage whenever someone is ready to create a life they love.” —David Kelley, Founder of IDEO “An empowering book based on their popular class of the same name at Stanford University . . . Perhaps the book’s most important lesson is that the only failure is settling for a life that makes one unhappy. With useful fact-finding exercises, an empathetic tone, and sensible advice, this book will easily earn a place among career-finding classics.” —Publishers Weekly From the Hardcover edition.
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.

Test-Driven Development (TDD) is now an established technique for delivering better software faster. TDD is based on a simple idea: Write tests for your code before you write the code itself. However, this "simple" idea takes skill and judgment to do well. Now there's a practical guide to TDD that takes you beyond the basic concepts. Drawing on a decade of experience building real-world systems, two TDD pioneers show how to let tests guide your development and “grow” software that is coherent, reliable, and maintainable. Steve Freeman and Nat Pryce describe the processes they use, the design principles they strive to achieve, and some of the tools that help them get the job done. Through an extended worked example, you’ll learn how TDD works at multiple levels, using tests to drive the features and the object-oriented structure of the code, and using Mock Objects to discover and then describe relationships between objects. Along the way, the book systematically addresses challenges that development teams encounter with TDD—from integrating TDD into your processes to testing your most difficult features. Coverage includes Implementing TDD effectively: getting started, and maintaining your momentum throughout the project Creating cleaner, more expressive, more sustainable code Using tests to stay relentlessly focused on sustaining quality Understanding how TDD, Mock Objects, and Object-Oriented Design come together in the context of a real software development project Using Mock Objects to guide object-oriented designs Succeeding where TDD is difficult: managing complex test data, and testing persistence and concurrency
