        Product details SICA 5 C 1 CS - 4

        SICA 5 C 1 CS - 4 5" 100W Coaxial Woofer 4 Ohm

         

        This SICA 5 C 1 CS - 4 coaxial woofer is built around a pressed sheet steel basket that ensures mechanical stability and longevity. The woofer features a treated paper cone and a rubber surround, combining lightweight construction with the damping required for accurate transient response. The tweeter utilizes a Macrofol dome and a neodymium magnet, providing crisp, extended high-frequency performance. Together, the integrated design helps simplify speaker system construction and reduces installation complexity.

         

        Designed for use in a wide variety of speakers, the SICA 5 C 1 CS - 4 is an excellent choice for compact or multi-way systems where space-saving and full-range audio are critical. Its 4-ohm impedance and 25 mm voice coil are compatible with a broad range of amplifiers, making this driver suitable for both new builds and upgrades in home audio, studio monitoring, or custom installations.

         

        With a sensitivity of 91.5 dB and a maximum linear excursion of +/-2.0 mm, this driver provides impressive output while maintaining low distortion. The use of ferrofluid in the tweeter’s air gap enhances cooling and reliability, ensuring consistent high-frequency response even during demanding operation. The 1.10 T flux density and 4.88 Wb/m force factor reflect a well-engineered magnetic system for dynamic, punchy sound.

         

        The SICA 5 C 1 CS - 4 is a versatile component for audio enthusiasts and professionals seeking reliable audio components for custom projects. Its coaxial design reduces the need for separate tweeters and woofers, saving space and simplifying crossover requirements. Ideal for DIY speaker builders or system integrators, it offers a solid foundation for high-quality sound reproduction in a variety of acoustic environments.
