SICA 18 K 4 PL 8Ohm 18€ 2400 W Subwoofer
This 18-inch woofer stands out with its advanced materials and meticulous construction. The neodymium magnet circuit reduces overall weight while delivering powerful magnetic flux, and the aluminum die-cast basket ensures structural stability during intense operation. The sandwich voice coil, wound on a fiberglass former, offers both strength and efficient heat dissipation, which is crucial for high-power applications. The cone is treated with an autoclave waterproof process, making it especially suited for environments where humidity or moisture could otherwise compromise performance.
Performance-wise, the SICA 18 K 4 PL 8Ohm offers a frequency response from 35 Hz to 700 Hz, providing deep, punchy bass that is ideal for speakers used in live sound, club installations, or large venues. The double Konex spider with progressive waves and the DAR cloth surround enable extended excursion and precise cone control, translating to lower distortion and better bass accuracy even at high output levels. With an Xmax of ±6.5 mm and a maximum linear excursion (Xvar) of ±10 mm, it handles dynamic transients with ease.
Thanks to its sensitivity of 97.8 dB at 1W/1m, this subwoofer is highly efficient, requiring less amplifier power to achieve significant sound pressure levels. This makes it compatible with a wide range of amplifiers, fitting well into both new system builds and upgrades for existing professional PA setups. Its 8-ohm impedance and robust mounting hardware further enhance versatility and installation flexibility.
The SICA 18 K 4 PL 8Ohm is ideal for DIY audio enthusiasts and professionals looking to build or upgrade high-performance subwoofer enclosures. Its durability, combined with premium features like autoclave cone treatment and a ventilated magnet to reduce power compression, also make it a reliable choice for demanding home audio installations, studio monitors, or custom sound reinforcement systems.
