Replace Your Blown JBL 2431H Diaphragm

A damaged compression driver diaphragm can cause distortion, reduced high-frequency output, buzzing, crackling, or complete loss of HF output. Replacing the damaged diaphragm allows you to rebuild the existing JBL 2431H driver rather than replacing the complete compression driver.

For customers who want to maintain their JBL loudspeaker with factory components, the genuine JBL D8R2431 diaphragm is the recommended replacement for the original 2431H diaphragm.
