But, the problem was I was always the best mathematician among the engineers. So, instead of doing the typical circuit theory, my professors wanted me to work with Maxwell's equations and wave propagation that none of the regular engineers liked, but I liked it. So, I ended up doing a Masters Degree at Oklahoma State in antenna research which, interestingly, involved an acoustic wave being excited in a plasma by an antenna. Later, I was admitted to Stanford in their Ph.D. program in EE I worked in a very low frequency radio propagation group that was interested in studying lightning as received by earth satellites, which involved computer calculations and spectrum analysis. And as it turns out, the VLF radio frequency spectrum was the same as the audio spectrum, so we used many types of spectrum analysis machines there, such as FFl"s, tracking wave filters, etc. I learned how to apply them, which later on turned out to be a good background for analyzing acoustics and speakers. I did a Post Doc in Atmospheric Physics the University of Florida where I worked with atomic cross-section modeling for atmospheric species.

Then I was hired by The Aerospace Corporation to work in very low frequency research doing some of the same things I did at Stanford. Later at Aerospace I went to a satellite group that worked with small scientific satellites, where I did the planning on how you put experiments together for satellites.

With the downturn of aerospace work here, I found myself in 1994 having to find andother job. So, at that point, the loudspeaker business was taking off, and I said, "Well, if I don't do it now, I'll never do it." So, for the past years I've been gainfully employed in my business called Edgar Horn, building and designing horns for people.

Excerpted a huge interview in Positive Feedback, "A Journal of High-End Audio" with Bruce Edgar Bruce: When I was a teenager in the mid 50's, one my first speaker projects was from an article in Popular Electronics about a little corner horn speaker. I now call it a pseudo horn because it used two 5" speakers in a quasi-backloaded horn. When I look at that project now I can see just how much folly and fiction there was in it, but it sounded OK, and at the time I didn't know the difference. I also played trumpet and French horn in high school bands, and so I have always been intrigued by horns. The band experience gave me a sense of how much power is in a real musical instrument, and I remember I used to love sitting in the band just listening to all the instruments playing. Today horn loudspeakers are the only speakers that I have found that convey the acoustical power from typical musical instruments. In terms of educational background, I went through Electrical Engineering (EE) School at Oklahoma State University in the early 60's. Originally I thought I wanted to go into physics, but a number of physicists in the oil industry that I knew growing up told me that engineers make more money. So I went into engineering. But, the problem was I was always the best mathematician among the engineers. So, instead of doing the typical circuit theory, my professors wanted me to work with Maxwell's equations and wave propagation that none of the regular engineers liked, but I liked it.
