tuning dt0w's
i have a factory set of dt40w's that came poorly tuned are are ringing. dz has given me some excellent clues behind the scenes, and i have adam's scanner tuning guide standing by.
what i don't have is a description of the controls on the amp boards. my galvos didn't come with any documentation and the board isn't labeled.
a latte for anyone who can provide a clue for me!
thanks!

suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
