SICA 5,5 H 1,5 CP 8 5.5 Inch Woofer 8 Ohm

This SICA woofer is meticulously engineered for integration into speakers and studio monitors, offering a nominal diameter of 140 mm and an 8-ohm impedance. The assembly utilizes a die-cast aluminum basket for rigidity, a paper cone with special damping treatment for natural tonality, and a solid paper dust dome to maintain clarity throughout the frequency range. The robust construction and quality materials ensure consistent performance and long-term reliability, making it a top choice for both home audio and professional sound environments.

Performance is a standout feature, as the SICA 5,5 H 1,5 CP 8 delivers a sensitivity of 86.9 dB (1 W/1 m) and a broad frequency range from 48 Hz up to 5,500 Hz. The voice coil’s 38 mm diameter and 15 mm winding depth, combined with a powerful 0.98 T magnetic flux density, allow the driver to handle up to 240 W of program power effortlessly. The ventilated magnet design helps reduce power compression, ensuring stable output even during extended high-level playback, while the double asymmetric rubber surround contributes to precise cone movement and reduced distortion.

Thanks to its linear excursion of +/- 4.5 mm (Xmax) and a high compliance suspension, this woofer is well suited for use in vented or sealed enclosures. Its frequency response and smooth roll-off make it an excellent candidate for two-way and three-way systems, as well as custom woofers in high-fidelity DIY projects. The mounting dimensions (overall diameter 148 mm, baffle cutout 113 mm, total depth 71.5 mm) provide flexibility for installation in a variety of cabinet designs, including both retrofit and new builds.

Whether you are building a reference-grade studio monitor, upgrading your home audio system, or designing your own DIY speaker kit, the SICA 5,5 H 1,5 CP 8 offers the performance and reliability needed for professional results. Its advanced magnet circuit and cone treatment technologies minimize distortion and coloration, making this driver an excellent choice for audio enthusiasts and speaker designers seeking uncompromising sound quality.
