Got a blown driver in your Turbosound TMS2 or TMS4 speaker cabinet? This is the exact replacement diaphragm you need for the CD-102 and CD-101 bolt-on compression drivers. The diaphragm is the critical moving part inside the driver that actually produces the sound, and over time or with overload, it can fail. This one is built to the original specs with a 16-ohm impedance, ensuring it matches your cabinet's crossover network correctly. It’s designed for a direct bolt-on installation, so if you’re comfortable opening up your speaker and have some basic technical skills, you can save a ton of money compared to buying a whole new driver. Make sure your driver model is exactly CD-102 or CD-101 before ordering. Swapping in a fresh diaphragm can bring your professional speaker back to life with its original sound quality. A must-have spare for audio technicians, venue owners, or anyone responsible for maintaining a Turbosound PA system.
