Focal Sub 1000 F

Focal Sub 1000 F: active subwoofer with Flax woofer

A sealed active subwoofer made for home cinema: well-defined bass and a neutral tone in a compact cabinet.

The Flax cone

The 30 cm woofer has the Flax cone: a sandwich with a French flax fibre core between two thin glass fibre sheets, patented by Focal and presented in 2013. It is light, hence dynamic; stiff, hence firm in the bass; damped, hence neutral and uncoloured.

Amplifier and cabinet

It is driven by a 1000-watt BASH amplifier: the woofer has all the drive it needs. The sealed enclosure extends the low response, keeps the size down and removes port noise. It has stereo line inputs and a direct LFE input; power is always on or automatic.
