        Product description SICA 4 C 1,5 CP - 8 Coaxial woofer

        The SICA 4 C 1,5 CP 8+8Ω is a high-performance 4-inch coaxial woofer designed to deliver outstanding audio clarity and power handling in compact speaker systems. With a robust 200 W continuous program power, this coaxial unit integrates a 1.5-inch LF voice coil on an Epotex former and a 1-inch HF treated silk dome tweeter, making it ideal for demanding applications where space and fidelity are key. Its carefully engineered construction, including a die-cast aluminum basket and advanced magnet circuits, ensures durability and precision for both home and professional audio projects.

         

        Highlights of the SICA 4 C 1,5 CP 8+8Ω

        • Coaxial design with 4" woofer and 1" silk dome tweeter for integrated full-range performance
        • High power handling up to 200 W continuous program
        • LF ferrite and HF neodymium magnet circuits for optimal efficiency and weight balance
        • Wide frequency response from 100 Hz to 18,000 Hz with 91.2 dB sensitivity

         

        Product details SICA 4 C 1,5 CP 8+8Ω

        SICA 4 C 1,5 CP - 8 Coaxial woofer 4" 200 W

         

        This advanced coaxial woofer combines a precision-engineered low-frequency driver and a high-frequency silk dome tweeter in a single compact chassis. The LF voice coil uses a copper winding on an Epotex former to ensure excellent heat dissipation and mechanical reliability during extended high-power operation. The tweeter’s treated silk dome and neodymium magnet provide smooth, natural highs, while the treated cloth surround offers additional longevity and resistance to environmental wear.

         

        Designed with versatility in mind, the SICA 4 C 1,5 CP 8+8Ω is perfectly suited for modern speakers and compact audio systems. Its 106 mm diameter and shallow 68.6 mm depth make it easy to integrate into a variety of enclosures, including vented box designs. An optimized crossover frequency of 3.0 kHz ensures seamless integration between woofer and tweeter, and the included mounting hardware allows for straightforward assembly in DIY or custom applications.

         

        The coaxial configuration delivers point-source sound reproduction, minimizing phase cancellations and off-axis response issues often encountered in multi-way systems. This makes it a prime choice for audio enthusiasts and professionals seeking improved imaging and clarity in compact loudspeaker builds. The recommended cabinet design of 1.8 liters internal volume with dual 22 mm vents at 70 mm length supports extended bass response without sacrificing midrange articulation.

         

        For optimal performance, SICA offers a dedicated 2-way assembled crossover precisely tuned for this driver, featuring an 18 dB/oct high-pass and 12 dB/oct low-pass slope - SICA ZC01920. This ensures balanced sound and protects both woofer and tweeter during high-output use. Integrating this coaxial woofer into your next DIY speaker kit project or upgrading existing woofers will yield professional-grade sound quality and reliability for any home or studio environment.
