More likely the membrane is torn which over time happens. Using the speaker balance control see if you can ID which speaker is bad it’s also possible both are needed. Here’s the parts MacBook Unibody A1342 Speakers

Thank you Dan, I'm gonna check the part number on my computer and order it as both speakers are effectively bad.
