I have been an audio enthusiast ever since ham radio was shut down during World War II. My home in Lexington, Massachusetts is built around my 20,000 watt hi-fi system. The photo above shows 3 of my 5 speaker horns which contain 150 tweeters, 5 mid-range horns with dual drivers, 10 16-inch woofers, and 4 24-inch subwoofers. I started designing my 5-channel system in 1962 and it is almost finished.
After designing electronic circuits as a full-time consultant for 41 years I retired to part consulting in 2002. Equipment for which I designed circuits included: airborne, seaborne, audio, video cable TV, automotive, industrial control, medical, detection, laboratory instruments, function modules, space vehicle, and integrated circuits. Partial retirement enabled me to work 60 hours/week for more than 8 years at my passion, high-fidelity audio. During that time I developed audio signal processing software to improve the sound of my hi-fi, and incidentally become professional and consumer products. It has 1,400,000 long mathematical equations and now every one of them works.
