Focal 1000F Active Subwoofer

The Focal Sub 1000 F is a high-performance active subwoofer designed for Home Cinema applications, combining a 12-inch Flax-cone woofer with a powerful 1000W BASH® amplifier in a compact sealed enclosure. Focal describes the Sub 1000 F as powerful, reliable and ultra-compact, with the design focused on extending low-frequency performance while maintaining a controlled and clean presentation.

At the heart of the Sub 1000 F is a 30cm Flax sandwich-cone woofer incorporating a dual-magnet system. Focal states that the dual magnet improves linearity and ensures an optimal magnetic force is delivered to the voice coil. The Flax cone itself is designed around a combination of lightness, rigidity and damping.

The sealed cabinet uses thick panels, including a 40mm front panel, and incorporates a high-gloss lacquered finish. With a 24Hz–200Hz frequency response at ±3dB, a -6dB low-frequency point of 22Hz and adjustable crossover control from 40Hz to 160Hz, the Sub 1000 F provides the low-frequency extension and system integration required for a dedicated high-performance home theatre subwoofer.
