In Reply to: Wayne and crossover guys; a little help? posted by Till E. on January 16, 2003 at 16:21:00:
Wayne already sent me the 800 Hz schematic with values of R1, R2, and C1 for various rolloffs: 6, 9, 12, etc.
What I need is to figure out how to hook up this thing. I thought Ron's idea of getting the Eminence cross and changing the 3 values would be good 'cause I've done that before.
Would it be safe to say (as in live nude resistors) that everywhere a part crosses the line of another part that is a connection?
For example: the line that goes East from the bottom input crosses a line that says C4 so a 20uF 250 V cap connects to that wire, right?
There is also a resistor R3 that makes the same conection with one end and the other connecting toin series to a Cap C5 which connects to the woofer positive(?) terminal.And the the wire from the neg side of R3 connects to the neg woofer terminal. Yes? No?
Why is there a bumpy line across both driver symbols? The same bumpy line that signifies an inductor?
Anyone care to annotate the Pi Speakers Crossover Diagram with " now put tab 'A' in slot 'B'?"
Alternatively, has anyone drilled out the rivets holding the Masonite to the Eminence crossover PCB. Is there glue also? or would they come apart so I could "read" those connections?
