Original Loud Speaker for iPhone 11 iPhone 11 Pro iPhone 11 Pro Max

Product Name: iPhone 11 Series Bottom Speaker / Loudspeaker Assembly

Compatibility: iPhone 11 / iPhone 11 Pro / iPhone 11 Pro Max

Grade: OEM Pull (Genuine part harvested from donor devices. Fully functional, but may show minor signs of prior use.)

Replace this speaker assembly to resolve issues specifically related to audio output from the bottom of the device, such as:
No Audio Output: The bottom speaker produces no sound during media playback, phone calls on speakerphone, ringtones, or alarms.
Distorted or Crackling Audio: Sound is muffled, fuzzy, rattling, or distorted, especially at medium to high volumes.
Intermittent or Cutting-Out Audio: The speaker works inconsistently, cuts in and out, or audio fades unexpectedly.
Significantly Reduced Volume: Output is noticeably weak, tinny, or quiet even with volume settings maximized.
Complete Audio Imbalance (Stereo): When compared to the front earpiece speaker, the bottom speaker is significantly quieter or absent, destroying the stereo sound effect during media playback.
Physical Damage: Visible damage to the speaker grille, a torn speaker diaphragm, or debris/water damage blocking the sound output.

Professional installation is recommended.
After installation, you must thoroughly test:
Speakerphone & Call Test: Make a phone call and activate speakerphone. Verify audio is clear, loud, and free from distortion or cutting out.
Media Playback Test: Play a music or video file with a wide range of frequencies. Test at low, medium, and high volumes. Ensure the sound is clear, full-bodied, and without crackling or buzzing.
Stereo Balance Test: Play a known stereo audio track. Verify sound is balanced between the bottom speaker and the front earpiece speaker, creating a proper stereo image (cover the top and bottom separately to test each speaker).
Ringer & Alert Test: Test ringtones and system alert sounds to ensure they play loudly and clearly through the bottom speaker.
System Audio Test: Reboot the iPhone and test audio functions again to ensure stability. Check for any audio-related error messages in the system.
