HK Audio Fineo FO S218 BLK - 4000W 2 x 18-inch Passive Bass Reflex Installation Subwoofer with 4-Ohm Impedance and 3-inch Voice Coil in Black Finish

The HK Audio Fineo FO S218 is the most powerful subwoofer in the Fineo series, offering unparalleled bass performance with its dual 18-inch woofers, each equipped with a 3-inch voice coil. This robust subwoofer delivers deeper, louder, and stronger bass, making it an ideal choice for high-demand environments such as concerts, sports venues, and clubs. With a frequency range extending down to 33 Hz, the FO S218 ensures an incredibly low-end response that brings depth and clarity to both modern music styles and speech applications. Its flow-optimized bass reflex port enhances the low-frequency output, resulting in a clear and punchy bass response that complements the FO 12 and FO 15 mid/high units perfectly.

The FO S218's dual 18-inch drivers provide exceptional power handling, with a nominal power rating of 2000W RMS and a peak power capacity of 8000W. This makes it an excellent choice for large-scale events and installations where high SPL levels and extended bass response are essential. The subwoofer's omnidirectional dispersion ensures consistent bass coverage across the entire listening area, making it perfect for both live sound reinforcement and fixed installations.

Designed for flexibility and easy integration into various environments, the FO S218 can be used both upright and on its side, allowing for versatile placement options. It also features a practical cable duct that allows cables to be routed close to the wall, minimizing cable clutter and enabling easy installation in tight spaces. The subwoofer is protected by a full-surface, heavily reinforced steel grille that guards the bass reflex port against accidental or intentional damage, ensuring the longevity of the subwoofer. Additionally, the FO S218 is certified for ball impact resistance in line with DIN 18032-3, making it an excellent choice for use in sports facilities and other high-traffic areas.

The FO S218 is compatible with a range of DSP platforms and is optimized for use with amplifiers such as the Lab.Gruppen IPX series and LEA Professional. With dedicated DSP presets and filter sheets available for seamless integration with other HK Audio components, the FO S218 can be easily incorporated into larger sound systems. The subwoofer's robust MDF enclosure, coated with a high-quality acrylic enamel finish, is designed to withstand the rigors of touring and permanent installations alike. The unit also includes rubber feet for added stability when placed on the floor, and is available in a sleek black finish.
