Focal E 30 KX K2 Power Series 12″ dual 4-ohm voice coil subwoofer


The E 30 KX is a 30 cm (12″) subwoofer with very high power handling. It has an impressive SPL of 86.5 dB (2.83 V/1 m) and a sealed box or bass-reflex type enclosure of 28 to 35L! The E 30 KX subwoofer takes full advantage of the acoustic qualities of Kevlar® cones. Light, rigid and with excellent damping, they provide extremely dynamic bass. Their yellow colour is legendary of the K2 Power line’s identity. All the components used for this subwoofer have been optimised to improve performance. The cone is fixed to the frame using a new robust and very reliable rubber suspension, whose exclusive shape has been optimised to provide very high excursion. The aluminium frame has also been redesigned to improve voice coil excursion. All moving parts benefit from this excellent excursion, giving the subwoofer tight, punchy and dynamic bass. The oversized “Dual Magnet” has been given a new voice coil cooling system to improve cooling and also to improve the subwoofer’s performance and power handling. The progressive spider profile is designed to provide a full-bodied bass to increase linearity, precision and dynamic range.

  DYNAMIC BASS FOR YOUR VEHICLE The subwoofers used for the K2 Power have been completely redesigned. Each component is the result of extensive research in acoustics to push back the limits of performance, of power and of precision!


Precision and dynamics

The K2 Power Kevlar® cone, a product of unique expertise Made In Focal, is to this day second to none. Composed of an ultra-light foam structure sandwiched between a thin layer of Kevlar® aramid fibres, and a layer of glass fibres, the K2 Power cone combines three key factors of quality acoustics: Rigidity / Lightness / Damping, for precise and dynamic sound.


Used in JMLab Vega or Antea high-fidelity speakers, the K2 sandwich cone was introduced for the first time in 1986 with the use of Polykevlar. The Poly-K cone is composed of two layers of aramid fibres, applied to either side of a hollow micro-ball structure in order to improve the balance between weight, rigidity and damping.
