        Product details SICA 3,5 L 1 SL 4

        SICA 3,5 L 1 SL 4 Bass-mid woofer

         

        This 3,5 L 1 SL - 4 bass-mid woofer incorporates a 25 mm sandwich voice coil wound on an epotex former, ensuring both high thermal stability and efficient heat dissipation. The balanced neodymium magnet circuit contributes to a lightweight yet powerful magnetic assembly, which is crucial for portable and high-performance audio systems. The voice coil’s ventilation further reduces power compression, allowing for consistent output even during extended use.

         

        With a nominal diameter of 88 mm and a mounting depth that fits in tight spaces, this woofer is suitable for modern compact audio designs. Its net weight of just 0.2 kg helps minimize overall enclosure mass, making it perfect for portable or lightweight woofers and small format DIY projects. The nylon fiberglass doped basket and rubber surround ensure mechanical stability while resisting the effects of environmental changes.

         

        The SICA 3,5 L 1 SL 4 excels in both bass and midrange reproduction, offering remarkable clarity and detail across its frequency range. The surface waterproof treated paper cone and treated cloth dust dome add an extra layer of protection, making this driver suitable for use in environments where moisture or humidity could be a concern. Its frequency response and low distortion make it ideal for main or satellite roles in multi-way home audio and professional PA systems.

         

        Installers and DIY enthusiasts will appreciate the straightforward integration of this woofer into various DIY speaker kit designs as well as custom enclosures. The unit’s technical parameters make it a strong candidate for crossover networks and active speaker setups, while its robust build quality ensures years of reliable performance in demanding audio components applications.
