SICA 12 E 2,5 CS 8Ω 12″ 600W Professional Woofer

 

This 12-inch woofer is part of SICA’s professional series, designed to deliver powerful and accurate bass performance. The use of a copper voice coil and Kapton former enhances both durability and heat dissipation, making the unit highly reliable even under heavy loads. The pressed sheet steel basket adds rigidity, while the ferrite magnet ensures strong magnetic flux for precise cone control.

 

With a rated power of 300 W AES and the ability to handle 600 W continuous program power, this driver is an excellent choice for high-output speakers and custom sound reinforcement solutions. The extended excursion (Xmax ±4.5 mm) and robust surround allow the woofer to reproduce deep, punchy bass without distortion, making it suitable for a wide range of music genres and environments.

 

The SICA 12 E 2,5 CS 8Ω is well-suited for use in vented or bass reflex enclosures, with optimal performance in a 45-liter box tuned to 55 Hz, as shown in its frequency response data. Its Thiele & Small parameters allow easy integration into both new and existing woofer designs, offering flexibility for system builders and DIY enthusiasts alike. The 8-ohm impedance makes it compatible with most modern amplifiers, ensuring seamless integration into multi-driver setups.

 

Whether you’re upgrading your PA system, building a new DIY speaker project, or seeking a reliable replacement for professional audio installations, the SICA 12 E 2,5 CS 8Ω delivers performance that meets the needs of demanding users. For those seeking a complementary solution, consider pairing it with the 15 E 2,5 CS – 8 bass-mid woofer for extended low-frequency response and balanced sound in multi-way systems.
