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.

Some photos in this guide are from a different model and may contain slight visual discrepancies, but they won't affect the guide procedure.

    • Completely power off and unplug your MacBook Pro before you start. Close the display and flip the entire laptop upside-down.

    • Use a P5 Pentalobe driver to remove eight screws securing the lower case:

    • Four 9.3 mm screws

    • Four 5 mm screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

    • Clean up any remaining adhesive from the frame before installing new adhesives.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.
