Introduction
Use this guide to replace one or both speakers in your MacBook Pro 14" 2021.
Replacing the speakers requires you to remove the logic board and fans. Removing the battery is optional but recommended to prevent bending or puncturing the battery cells adjacent to the speakers.
For your safety, discharge the battery below 25% before disassembling your MacBook. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
You'll need replacement adhesive in order to complete this repair.
