Yay! Audio knowledge! I've met so-called "geeks" who will look at you funny if you start talking about "frequency response" -- but they'll talk your ear off if you remind them about the frequency domain and Fourier Transforms. Back in the late 20th century, just about everyone who was tech savvy seemed to know some basics about sound. Nowadays, I wonder if the whole Monster Cable/coathanger thing has made some people filter out everything sounding like audio knowledge as "woo." Not all of it is. A lot of it is physics.

Back in the 80's, designing and building your own speakers was a suitable project for high school students. Still is.
