Keep in mind that I ask these questions simply out of curiosity. I have absolutely no hidden agendas, nor am I looking for any negative judgment to put on you. It's just the way my mind works.
1- Do you have formal education, or a mentor, in areas relating to what you do as far as speaker engineering is concerned?
2- How did you get started in this business, was it something that you kind of stumbled into out of a hobby that you got into?
3- When your DIY business becomes really(as it seems to be doing)successful, have you considered what you will do if you are approached by one of the big corporations that want to buy your company?
