Logitech z323, one of the speakers wont work. Can it be fixed?

[ThanosM]

I have the logitech Z323 sound system and one of the speakers have fallen of of my desk for several times.
When i put the volume at high i can listen to electric sound coming out of it, but no sound when listening to music.
I opened it up.The wires are fine.
Can this be fixed or i should buy another speaker?

Yes, i have checked the connectivity, same thing at every source.

It has been more than 3 years.
