Ouch! Good to know - thanks! Interestingly, my floor towers are one number away on their serial numbers, so they were produced at the same time. I'm not sure if it's safe to assume that they'll match better since the lot of components may be from the same batch, but I thought it was interesting. However, that was another reason why I wasn't excited about the thought of replacing the tweeter. Upon upgrading my system (years and years down the road), I'll just reduce the price of them a bit to account for the small dent.
