SICA CD 78.26/245 - 8 1" Compression Driver 8 Ohm
This compression driver features a robust design with a 25 mm voice coil wound on a Kapton former, providing both durability and efficient cooling for high-output scenarios. The tri-acetate diaphragm further enhances sound clarity, enabling the driver to reproduce crisp and articulate high frequencies across a wide range. With a 78 mm nominal diameter and compact mounting dimensions, it easily fits into various enclosure types and professional audio horns.
Performance is a key advantage of the CD 78.26/245 - 8. It offers a continuous program power handling of 32 W and a rated AES power of 16 W within the 2,500 to 20,000 Hz frequency range. The high sensitivity rating of 105.5 dB at 1 W/1 m ensures that even lower-powered amplifiers can drive this compression driver effectively, making it an excellent choice for both new builds and retrofit applications in audio components and home audio systems.
Designed for precision, the ferrite magnet circuit produces a flux density of 1.56 T, contributing to the driver’s dynamic response and low distortion characteristics. The recommended minimum crossover frequency is 2.5 kHz, making it compatible with a wide variety of crossover networks and high-pass filters—an important aspect for integrators and DIY enthusiasts working on crossover components or DIY speaker kits.
For builders and system designers, the SICA CD 78.26/245 - 8 offers flexible mounting options with four 4.5 mm holes on a 95 mm diameter and two M5 holes on a 76 mm diameter. Its net weight of 0.6 kg and overall dimensions of 78 x 88.5 mm ensure easy integration into most enclosures. Whether used in professional PA systems, studio monitors, or high-fidelity home audio environments, this compression driver provides outstanding value and performance for demanding audio components applications.
