Thanks for your note. You are correct, that all upstream components have been ruled out. I checked my original TIVa schematic from years ago, and although the online copy is difficult to read, I believe the original shows the midrange resistance as 3 ohms (exactly what mine measures), not 5 ohms.
I like your work-around with the additional resistor to reduce the other channel, however the bad channel exhibits a suck-out in the midrange relative to the woofer and tweeter, so I'm afraid I'd then make both channels sound bad!
Best regards,
Mike
