I have a couple 3 way crossovers from a pair of old JVC speakers. There seems to be one lead straight through from +, and two going through caps, then resistors, in series. I'm trying to figure out which lead is for which driver, and if possible what the cross over frequencies are. The traces are:
+ -----------------------------> Red
+ --- 6.8 uF ----- 3.3 ohm ---> Yellow
+ --- 1.5 uF ----- 3.3 ohm ---> Green
Thanks for any help.

Hi!
Very little info in your description..... What is the size of the box, the diameter, type (cone, dome), impedance of the drivers. Generally it is a kind of x-over used in el cheapo type boxes, where you run the woofer full range, and use a very primitive resistor attenuated 1st order filter for the mid and the tweeter. Some pictures maybe?

There is no box. There is nothing but the xovers. The speakers they were in came with an amp rated at 120 Wrms per channel into 8 ohms and the speakers were 8 ohm.
That makes sense as the yellow is shorter than the other two. The xover is mounted to the spring loaded speaker wire connectors. It was installed in the middle of the back side of the speaker, with the mid much closer. And I can't see filtering the woofer but not one of the others.
Thanks.
