This 1.4 inch diaphragm 1inch exit compression driver is for use in high quality sound reinforcement systems. The polyimide surround allows reliable operation in 2 way systems with lower crossover points. The titanium diaphragm is coated with a light, thin layer of unique damping material giving the driver an unusually smooth sound. All of the materials resist environmental factors of heat, vibration and aging ensuring many years of stable performance.
