I recently saw http://www.youtube.com/watch?v=Yd3hzYAJzOo&w and i want to make that.
I read the schematic at http://www.uploderx.net/dphrag/SCHEMATIC1___PAGE1444.jpg (that link doesn't work, use this one: http://www.buildlounge.com/wp-content/uploads/2011/10/xy88F.jpg for it, but, I'm still quite confused.
The parts that are the most problematic to me are the high, low, and mid pass filters. i don't understand what they are, and how there made.
If anyone could help me, thank you.
