Well, the midrange in one of my studio 40s just stopped working recently. I switched the woofer and midrange to see if it was the driver, and it wasn't: the midrange fired just fine when attached to the woofer wires, while the woofer sat dead silent when attached to the midrange wires. So something is wrong with the speaker's internal electronics and I live a thousand miles from the nearest authorized repair facility. Does anyone have any idea what could be wrong in there and what I should do about it? As an aside, as the second set of Paradigms to go bad on me, this is not a brand I will be buying in the future. . . .
