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. To decide how to act in the event of a collision, you should visit the ICOOLA service center, here you are diagnosed with a smartphone for free.
