Hartley H.A. Hartley's Audio Design Handbook

New York: Gernsback Library, 1958. — 130 p.The aim of this book is to bring together in compact form all the material necessary for designing an audio installation of the type known as "high fidelity." Within the limitations of one volume it is impossible for it to be complete; nor is it necessary that is should be so.
There is a vast amount of matter available for reference and study. Apart from the numerous books treating high fidelity as a separate branch of audio engineering, there is the whole range of standard textbooks and innumerable articles in the technical magazines.
