Active crossovers are used by almost every sound reinforcement system and every recording studio monitoring set-up; but the use of active crossovers is rapidly expanding. This new edition, presents all the updates to loudspeaker technology and crossover design. The edition expands on loudspeaker configurations and design issues, sound reinforcement issues, more on lowpass and highpass filters, and may other filters. This new edition is a must read for anyone wanting comprehensive practical knowledge.

Review :
"Best known for his work in audio power amplifier design, Self has also devoted a good deal of study to small-signal circuitry. He begins here by pointing out that almost everyone who knows agrees that audio systems using active crossovers sound better than those using passive crossovers. He predicts that this feature will be the next big step in high fidelity sound reproduction, but says his explanations could be useful for holdout designers of passive crossovers as well. Among his topics are how loudspeakers work, crossover types, lowpass and highpass filter characteristics, equalization, subwoofer crossovers, line inputs and outputs, and power supply design."--Reference and Research Book News
"This book includes valuable information with virtually every page revealing nuggets of specialized knowledge never before published. With this book you will learn about the use of capacitance multipliers in biquad equalizers; opamp output biasing to reduce distortion; the design NTM notch crossovers; the design of special filter-driver crossovers, and more."--Wonderpedia.com
"A crossover unit gives the right frequencies to the right speakers so they can create the best sound. Using a crossover unit is more than just plug-and-play. It's plug-andconfigure. It's a science. Whether you already have a crossover unit or are looking at upgrading your existing speaker system, consider adding 'The Design of Active Crossovers' to your bookshelf. I've added it to mine."--ProSoundWeb.com
