My bass are broke, how to fix it?

First hello, and sorry for my english.

One day ago I drop my JBL xtreme from my table on the ground. Since, the right bass on the side make a weird sound. I never fixed anything, but I loved this JBL. I would be very happy if someone could help me. Is it repairable? And if, can I do it with little Skills?

Thank you for your Time
