Inspection and preventive maintenance

Visually inspect the diaphragm and the voice coil.
If any damage is visible, replace the diaphragm.

Clean the air gap thoroughly.
Use double-face adhesive tape to remove any particles.

Perform the diaphragm reassembly procedure.
Apply the recommended torque.

Repeat the listening test.
If the problem persists, replace the driver.
