I'm not sure if the Edge used the same tweeters, but the Focus, Fusion, and Escape, if I recall, shared the same tweeters (front and rear). The local dealerships want me to schedule an appointment 3-4 weeks out and to leave the car there for at least 1-3 days due to the amount of vehicles in their queue. I tried to get them to fix the door module and ACM issues without an appointment, and they said I'd have to leave my car there for at least 4 days. I told them it takes about 15-20 minutes total as it is pure software upgrade only. Anyhow, the tweeter seems to be working now, so I will just keep an eye on them. I was tempted to buy the MKZ tweeter as it is supposed to be a "Revel" system.
