This 1.75-inch replacement diaphragm from DS18 is specified for PRO-TW4L and PRO-TWX4 tweeters and rated for universal 8-ohm applications. It provides a direct repair option to replace a worn or damaged diaphragm while preserving the original tweeter assembly. Use it when rebuilding drivers to retain intended impedance and to avoid full driver replacement when the diaphragm alone needs service.
