Replacing the lower polyphonic speaker in the iPhone 11 Pro Max

Repair of a damaged polyphonic speaker on iPhone 11 Pro Max

The subwoofer or polyphonic speaker is responsible for playing audio when viewing media, as well as for playing when talking in loud mode. Its damage mainly occurs when hitting the bottom of the smartphone, or punching the mesh and the accompanying ingress of moisture. Preferably the repair is performed by a complete replacement with a new one or cleaning.
