One of the common problems with the speakers is muffled sound and this is mostly because of defective tweeters.

Some of the possible reasons a tweeter can fail is overload (excessive power), faulty crossover block,

or the coil being obstructed of moving freely in the magnetic gap as a result of sticky- dried out cooling liquid, or metal oxide built up in the magnetic gap. 

Depending on the damage, the tweeter dome/diaphragm can be repaired or replaced.

It is recommended to check/test the crossover blocks as well to avoid further damages to newly repaired tweeters.
