[QUOTE="Paul Lewendon, post: 216710, member: 13612"] Sometimes a coil can just get "weak". I see that when fixing speakers, the tweeter will look alright, but the coil is just fading away. Measuring the impedance/resistance of each of them might tell you that, but not necessarily. They should be pretty close, whichever the resistance of the good one is. Even just a little swelling of the coil can slow it down, but not enough to physically feel it. If it's a half decent tweeter, the coil may be replaceable, that'll save some money, because aside from some trauma like overheating or dropping, the magnet part rarely fails. Coils can range anywhere from $20 and up, and the whole thing can be anywhere around $100 and up, naturally the brand, etc can throw that number off, or even make it so the coil isn't replaceable.
