Description
This 1.75 inch diaphragm 1inch exit compression driver is for use in high quality professional sound reinforcement systems. The magnet system was designed for high sensitivity while keeping the weight and cost to a minimum. The 3-slot phasing plug and aluminium wire voice coil give improved HF energy. The titanium diaphragm is coated with a light, thin layer of unique damping material which results in a smoother sound, especially when driven hard. All of the materials resist environmental factor of heat, vibration and ageing ensuring many years of stable performance.
Features
- 1" throat with 2/3-bolt mount for use with many popular horns.
- Damped titanium diaphragm provides smooth and detailed response.
- Suitable for use with crossovers as low as 1,500 Hz.
- Ideal for use in high output 2-way and 3-way designs.
