I would also like to know whether non replacement of damaged speaker would affect any other parts/internal applications.

Hard to say.

Replacing a speaker is a fairly easy task. Look at the iFixit.com website for specific instructions for your MBP. You can save some money doing it yourself.

Ciao.

I have been experiencing issues with the left speakers on my MacBook Pro (13inch late 2013 model). Not sure what happened. It sounds blown so I had to switch the balance to use my right speakers. That solved the issue as a workaround solution, but doesn't address the fundamental problem. Just wondering if any other owners of the late 2013 model experiencing the same problem. That's quite a disappointment for having used it for less than 2 years.

I have got the same problem 😟 using right speaker only as well + bluetooth speakers ....

disappointed since out of warranty as well

I have the same problem too! This is very frustrating. Now that I know I am not the only one experiencing this, I can infer that the MacBook Pro speakers don't last. I have been using it for less than 2 years. 2 months ago, my left speaker started having distortion when I watch videos and listen to music. Then, I tried resetting PRAM and SMC but nothing changed. After that, I resolved to switching my output speaker balance slightly to the right to reduce distortion so that the output sound is audible. Today, both speakers – left and right – are gone for good. I don't know what to do except reading a solution on replacing the MBP speakers on iFixit website.

Well, hardware failures now affect consumers even though they pay so much for a high quality device. I have taken care my MBP for almost 2 years without any problems with other hardwares except the speakers. Now, the only solution is to use headphones or earphones. This definitely blow away the elegance, premium feel and sole purpose of using a MacBook Pro – being minimalistic.
