SICA 5,5 C 1,5 CP – 8 Coaxial woofer

This compact yet powerful coaxial driver is equipped with a 1.5-inch voice coil on a Kapton former for the low-frequency section and a treated silk dome 1-inch tweeter for the high-frequency range. The combination of ferrite and neodymium magnet circuits provides excellent efficiency and control, making it suitable for demanding audio applications. The robust construction, including a die-cast aluminum basket and a damped paper cone, ensures low distortion and reliable performance even at high output levels.

With its wide frequency range of 60 Hz to 20,000 Hz and a sensitivity of 89.8 dB, the SICA 5,5 C 1,5 CP – 8 delivers clear and balanced sound across the spectrum. The Double Asymmetric Rolls Technology (DAR) rubber surround, along with damping cone treatment, extends the driver’s excursion capabilities and improves durability. These features make it a prime choice for building or upgrading high-quality speakers where both clarity and punch are required in a compact format.

The coaxial design integrates the woofer and tweeter in a single unit, which allows for superior point-source performance and coherent soundstage, especially important in nearfield and compact audio setups. This makes the SICA 5,5 C 1,5 CP – 8 suitable for home audio systems, studio monitors, and high-end audio components. Its mounting flexibility with a 148 mm overall diameter and 73.5 mm depth further enhances its ease of installation in various enclosures.

For optimal integration, SICA offers a dedicated 2-way crossover designed specifically for this coaxial driver, ensuring seamless frequency transition between woofer and tweeter – SICA ZC02810. The recommended vented box design with 9 liters internal volume and 58 Hz tuning highlights its adaptability in DIY and custom speaker projects. If you are seeking a reliable solution for upgrading or constructing compact high-performance DIY speaker kits, this coaxial woofer is an outstanding option.
