SICA Compression Driver with 1″ Throth Dia : 1.7″ Ferrite Voice Coil : 120 watt with Titanium Diaphragm CD 120.44 /640T

The SICA CD 120.44 / 640T Compression Driver is a professional high-frequency driver designed for PA systems, sound reinforcement, live performances, concert setups and other demanding audio applications. Featuring a 1-inch throat diameter, 1.7-inch ferrite voice coil and titanium diaphragm, it combines high sensitivity with dependable power handling to deliver clear and powerful high-frequency reproduction. With 120W power handling and 106.3 dB sensitivity, this driver is well suited to high-output horn-loaded speaker systems where efficiency and consistent performance are important.

High-Efficiency Audio Performance

With a sensitivity of 106.3 dB, the SICA CD 120.44 / 640T can produce high sound pressure levels efficiently when paired with a suitable horn and amplifier. Its 120W power handling capability makes it suitable for professional sound reinforcement applications that require strong and reliable high-frequency output. The 1-inch throat is designed for use with compatible horns, allowing the driver to be integrated into different speaker configurations according to system requirements.

Titanium Diaphragm for Clear High Frequencies

The titanium diaphragm provides a rigid and durable diaphragm structure designed for detailed high-frequency reproduction. It helps the driver deliver crisp and focused sound while maintaining controlled performance at higher output levels. This makes the CD 120.44 / 640T a suitable option for applications where vocal clarity, high-frequency detail and efficient sound projection are required.

Ferrite Magnet and Thermal Stability

The driver uses a ferrite magnet circuit with a copper demodulating ring, designed to provide reliable magnetic performance while helping control distortion. A 1.7-inch voice coil contributes to power handling, while the Kapton voice coil former supports thermal stability during demanding operation. The aluminium flat wire construction assists heat management and can help maintain consistent performance during extended use.

Designed for Professional PA Systems

The SICA compression driver is suitable for horn-loaded loudspeaker systems used in live sound, PA installations, concerts, theatres, events and other professional audio environments. When matched with the appropriate horn, crossover and amplifier, it can provide efficient high-frequency coverage and complement a larger low-frequency speaker system.

Its combination of high sensitivity, titanium diaphragm, ferrite magnet construction and robust voice coil design makes it a practical choice for speaker builders, audio technicians and professionals upgrading or repairing high-output sound systems.
