First, what does the comma mean between 0,43 in one of your equasions. Also, how do I solve it? there are four variables, and I only know two of them. Thanks

I'm confused with what you told me. I have never made a coil before, except for small 5-turn ones that said in the book to do 5-turns. If I wanted a crossover for a sub, which I do, I would use the equation N=(SR[a*u*u0/I])*20pi, right. (Its the one off of that website you sent me to. What are the v...

are there any Active crossovers that are for a sub?

passive

there used to be a site called mpfree.com that had a schematic to build a free mp3 player. The site no longer exists, though. if I can find the schematics, I'll post them on my website: www.mikaja.freeservers.com It may take me a while, so keep checking.

Does anybody know of a low pass (for a sub) crossover that is easy to build and requires no coils? Thanks for your help.

If I were to design the PCB layout and mirror it on the computer, which I did, would it work if I used an inkjet printer and printed on t-shirt paper then transfer it to the board? Thank you.

Thanks All of you for your help, but you are suggesting methods that require a laser printer. I don't have a laser printer, though. Is there any way do do this with an inkjet?
Thanks!

How do you transfer a PC board design from a magazine to a copper board. I bought a kit from radioshack and it said to use carbon paper then go over the circuit with a pen. That doesn't work, though. Thanks for your help
