14. Repair only one side of speakers?

14. Can I repair only one side of my speakers?
This is possible, of course, but it might not be a wise course of action:
  • The other speaker will soon be worn out as well.
  • If one side has a new surround, and the old surrounds on the other side is more or less decomposed, the sound will be uneven, which may be audible.
However, in special circumstances, it is possible that one side of the loudspeaker pair has always been exposed to the sun, while the other side was placed in a dark corner of the room.
