Hi everyone. Happy New Year!
Here is some updated info on our sub issues. Some improvement. Took the driver out, sealed 12" sw-12-04. Tested the resistance of the coils.
They jumped around a bit, and my meter is pretty cheap, but the driver coil was around 8 ohms, and the servo coil was around 21 ohms.
Before we took out the driver there was some output but next to nothing. After getting the driver out, putting it back in and out again, I noticed the clip on the neg servo coil wire was loose. Only to find out the clip broke off. We hooked the wires up directly to the spring input with bare wire and the output was much more audible. Not where I think it should be, but an improvement. I checked the driver coil wire connectors and they seem fine.
Ran out of time so I couldn't hardwire the driver coils to the spring clips.
I guess we are happier with some clean output, but wondering if the measurements are as expected.
Thanks for any advice.
Ben
