About this book
The Complete Handbook of Crossovers is the definitive reference for anyone who needs to split an audio signal cleanly and reliably. Whether you are designing a multi-amplified studio monitor, tuning a line array for a stadium tour, or upgrading the sound system in a 200-person club, this book delivers the concrete knowledge required to get the job done right. We move straight past the abstract theory and generic advice to explain how crossovers behave in real systems, how to read a manufacturers spec sheet for the figures that actually matter, and how to integrate these devices into your workflow without introducing hum, noise, or phase shift.
This is not a marketing brochure. It is a working manual built for the professional. Inside, you will find a complete breakdown of every crossover type, a clear methodology for choosing the right unit for your specific budget and application, and a step-by-step guide to installation and calibration. The book also addresses the realities of owning this equipment, with dedicated chapters on routine maintenance and a deep-dive into diagnosing and fixing the most common failures, from blown fuses to faulty op-amps.
For those looking to monetize their expertise, a dedicated chapter explores concrete business opportunities, including system design consulting, equipment rental, repair services, and private-label product development. The book concludes with a look at emerging trends in DSP hardware and network audio, along with the resources you need to stay ahead of the curve. A comprehensive FAQ and a plain-language glossary complete this essential resource, making it the only book on crossovers you will ever need.
Reader Reviews
Timothy Roberts
★★★★★This is the book I wish I had ten years ago. The chapter on understanding crossovers alone, particularly the explanation of why a control room's acoustic environment changes everything about tuning, is worth the price. It cuts through the forum noise and gives you airtight, practical guidance. I've already used the troubleshooting chart to chase down a ground loop hum on our main PA. This one stays on my workbench.
Betty Davis
★★★★★The information is solid, but I was expecting a bit more on actual wiring diagrams in chapter one. I get the theory, I just wish it dove into the visual setups sooner. The sections on choosing the right unit and the business opportunities were interesting, but I felt the later chapters were a little more rushed than the opening. An okay reference, but it reads a bit more like a textbook than a field manual.
Donald Smith
★★★★★A worthwhile purchase for a serious hobbyist like myself. I appreciated that it doesn't talk down to you and stays well clear of the usual hyperbole you get in audio literature. The walkthrough on calibration was clear enough to follow on a measurement rig, and the explanation of the difference between LR and Butterworth slopes in setting the crossover frequency was exactly the detail I needed. Four stars because I wish the maintenance chapter had more photos.
