Why are so many of you DIY speaker builders and designers located in the North? Is that were all the engineers live or something?
My theory is that is where the two "big dogs" of DIY retail are situated - Madisound and Parts Express. Meniscus is also "up north" and they are also a serious player. Zalytron is in New York. Solen is in Canada. I think the roots of DIY culture are just deeper - not because we are better at it, or more intuitively drawn to it or any other individual reasons, I just think accessibility was more widespread pre-internet, and even for some time after the advent of internet sales.
If I had not found a list of vendors in the back of a Weems book almost 20 years ago, I would not have heard of almost any of the vendors outside of Radio Shack.
P.S. - most of us in this hobby are not engineers, and many of us are not even employed in any kind of "technical" position. Truck drivers, warehouse workers, construction workers, accountants, lawyers, assembly line workers, unemployed full time students (moi), kids, retirees - I believe virtually the entire spectrum of employment is represented in our hobby - which is the reason it is so fascinating.
Next time I chat with one of the Texas folk, I will send him over this way. They have regular, small get togethers down there, in addition to a bigger event called Lone Star Audio Fest which features DIY and commercial stuff.
