Yes, speakers do "wear out". Electrical and mechanical components settle, shift or "change" with age. Since a speaker is a combination of those two aspects ( electrical and mechanical ), they are subject to frequency response abberations, loss of output, etc...
Much of this can be taken care of by updating / replacing the capacitors in the crossover and having the drivers reconed. Reconing a driver is VERY different than just "refoaming" one. Whereas refoaming simply replaces the old foam that might have rotted or been damaged somehow, reconing basically uses the original magnet and basket of the driver. This means that you have a new spider, voice coil, driven element, surround, etc... In effect, you've got a brand new driver so long as the original magnet was not damaged.
What you might want to check is linearity between the two speakers that you have. If you can put your system into mono mode and still swing your balance to one side at a time, place the speakers side by side and do some SPL measurements using test tones. Measure and chart one speaker and then do the same for the other. So long as the two speakers measure pretty close over the entire testing range, i would not worry about it too much. Sean
