The right-hand and left-hand drivers both get the same signal (the middle driver is the tweeter, which handles the highest frequencies). A burning smell from a driver sounds like a significant failure. Did the left driver still work? If not, I'd suspect a failure in the crossover network, but if it still worked than it was just that one driver that died.
Not on the LSiC, the left side plays only bass while the right side plays mids and bass.
BTW, good job on trouble shooting though.
