Is the crossover in the speaker ok?? Difficult to check, but a possiblity.

Could be a shorted capacitor in the crossover, does one speaker sound much "brighter", possibly even somewhat harsh at the top end?
If the power amp is oscillating at high enough frequency, that will also cause damage to the tweeter, without being (very) audible.
