SICA 2,5 H 0,8 SL 8 2.5″ Bass-mid woofer 8 Ohm

 

This versatile driver offers a powerful audio solution in a small package, making it especially suitable for applications where space is a premium. The neodymium magnet circuit ensures a high flux density of 1.30 T, providing impressive efficiency and a sensitivity of 85.6 dB at 1 W/1 m. This makes it an excellent candidate for use in compact speakers that require both clarity and punch, such as studio monitors or multimedia systems.

 

The SICA 2,5 H 0,8 SL 8 stands out with its robust construction, utilizing a pressed sheet steel basket, a 0.8-inch voice coil with a Kapton former, and a copper winding. The cone and dust dome are made from specially treated paper, while the surround is crafted from treated cloth, offering both durability and a natural sound signature. The DT cone damping treatment helps to minimize unwanted resonances, resulting in a smoother frequency response and reduced distortion.

 

Designed for flexibility, this driver is well-suited to a wide range of audio projects including DIY builds, upgrades, and custom installations. Its compact size and high performance make it ideal for integration in desktop audio systems, portable sound solutions, or as a dedicated midrange in multi-way setups. The ventilated magnet system (VM) further enhances its thermal management, reducing power compression and enabling consistent performance even during extended listening sessions.

 

For audio enthusiasts and professionals seeking reliable and high-performance audio components, the SICA 2,5 H 0,8 SL 8 is a compelling choice. Its technical characteristics also make it a popular option in DIY speaker kit projects and for those looking to experiment with acoustic measurements. With its well-balanced design and focus on audio clarity, this driver is engineered to meet the needs of modern sound reproduction in both home and studio environments.
