Troubleshooting 1 Mid on an older Infinity Qb Speaker
I have a pair of older Qb(s). The mid on one is not working. Any thoughts on how to troubleshoot it, and if it needs replacing where to search for one?
Thanks,
Brian

Put a DVM across the midrange positive and negative connectors and see if there is continuity through the voice coil. That will tell you if your voice coil is open or not.
