Introduction to Loudspeaker Design: Second Edition

By John L. Murphy

Book Overview

"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"--

I Finally Understand How Loudspeakers Work!

Ever wonder why you can't make a tiny loudspeaker that has lots of bass? This book explains why a good sounding loudspeaker is a compromise between the size of the box, how loud it'll play and the amount of bass you'll get out of it. Lots of good information. Straight forward and east to follow.Highly recommended.

Ever wondered what a Q(ts) is and shy to ask?

This book is a good self-start on loudspeaker building. It tells WHAT are the things you have to look for in designing a working loudspeaker; there are many conflicting issues to address and the author states all of them clearly, not assuming the reader has a degree on the subject. This alone is a good reason to read this book. All popular box designs are explained and also some not-so-popular. It misses transmission lines, TQWT, horns and the like but this work is intended to be introductory. The explanation of Small-Thiele parameters is concise but clear. Most diagrams in the book are screen prints of the software program the author created (a good one in my opinion) and surely the book is a good software complement. The software does not cover the exotic designs that are missing in the book too. Some parts, like using a stetoscope to point-and-shoot enclosures behaviour are fun and intriguing. Having said all that, what I miss is WHY should I prefer an enclosure with a specific driver, WHAT parameters should I look for in a driver (assuming a given enclosure) and HOW do I have to orient myself in determining what is the best design for a given room/taste/sound/budget, real-world examples that is. But all in all the book is a easy-reading, good starting point on loudspeaker design that guarantees not to disappoint you, giving an overall outlook on the subject and clear useful technical knowledge to start with.

I learned a lot from this book

I've been working with loudspeakers for a long time but I sure learned a lot from this book. I was having trouble with speaker theory regarding the enclosure. But now after reading this I feel like I have a real grasp on the subject for the first time. The chapter titled "Loudspeaker Basics" really taught me what the box does and the design tradeoffs involved. I thought it explained the Thiele Small parameters clearly.I bought it mostly because of the good review in Speaker Builder magazine and really enjoyed reading it.

Good tutorial book on the subject

Murphy has done a better than average job of pulling together the technical considerations of loudspeaker design. He focuses on closed and vented designs sufficient to allow the first timer a fighting chance at successfully designing and building a speaker. The use of symbols is less than admirable, frequently mixing lower case and upper case symbols (see "F(sc)" on pp 48 v. "f(sc)" on pp 26). Proofreading would have made the book more enjoyable ("sign wave," pp 47). Editorial comments aside, if you want a relevant and timely book for the beginner this is it.
