The speaker cone in this subwoofer uses Flax Technology. Flax is an environmentally-friendly textile with astonishing structural properties that make it particularly suitable for sound production. It is light, stiff and well damped. In general terms, flax membranes provide greater neutrality of timbre and better sound definition.
Evolved from the Flax cones developed for the Aria 900 speaker range, the cone membrane in the Sub 1000 F features a new, even more rigid construction. Two sheets of 160 g/m2 fibre glass and a 250 g/m2 flax core. It is able to withstand the high demands associated with subwoofers.
The Sub 1000 F subwoofer also features a coil/driver unit that is optimised to keep the coil temperature as low as possible. This means the speaker gives well articulated bass, better dynamics and considerable SPL power (103.5 dB / 1 m @ 40Hz).
Focal’s Research & Development team developed a custom spider/suspension for the Sub 1000 F. Its dynamic behaviour is perfectly controlled, meaning that the bass is always controlled too, even with very long travel (up to 43 mm).
