JJ, I'm glad that you are excited about things and very passionate about speakers, I too was once like that at your age, but here's the thing. I've got close to a thousand emails to answer as I've had near next to no time to do any emails in weeks due to people being out sick, hurt, etc. I don't have time to answer hundreds of your questions a day, you have to take some initiative and read around the internet and educate yourself as I have told you numerous times. This is the do it yourself or "DIY" market where many things you have to read and figure out on your own. The information is out there and free for you to consult, you just have to google for it. If you keep sending the same email over, and over, and over, and over, and over it only makes the pile of email that I have to go through next week even bigger provided I'm not out sick with the plague that is going around the shop. My focus is on machining, building, and making things go out the door right now. Whether it be one handed, sick, hurt or whatever it is that has to be done. Filling orders takes priority over answering the hundreds of questions you have, I'm sorry I am not able to do that. Search around the internet...there's tens of thousands of hours of material for you to read.
