There are a number of problems that could cause your speakers to be blown out. You should definitely take a look at our troubleshooting page [[Jawbone JAMBOX MINI Troubleshooting#Section_Speakers_producing_poor_sound_quality|here]]. I'd try updating the JAMBOX's software before trying to open it up and replace anything. You can find Jawbone's software update guide [http://mytalk.jawbone.com/update|here]. If that doesn't work, you might have to open your device and replace the speakers. [guide|41694|Here] is the speaker replacement guide.
