Focal K2 Power 700W Shallow 10" Subwoofer Single Voice Coil 4-Ohm SUB25KXS

The fourth generation of K2 Power kits, with their emblematic aramid fibre cone, remain true to the precious and distinctive K2 DNA. The speaker drivers combine performance, power and style, whilst including patented innovations to deliver the very best. Designed, developed and manufactured in the Focal workshops in France, the subwoofer SUB 25 KXS has impressive power handling for such shallow depth. It has a shallow profile for high capacity without loss of energy.

SUB 25 KXS is an ultra-compact 10” (25cm) woofer. New for the fourth generation of K2 Power kits, it features a slim profile for even shallower depth without energy loss.
Sealed box or bass-reflex, this subwoofer gives impressive power handling and reliability for such a compact package.

Like all the K2 Power kits, SUB 25 KXS is equipped with the K2 aramid fibre cone. Born in 1986 and introduced into the car audio sector in 1992, the K2 sandwich cone is an exclusive Focal innovation, immediately recognisable by its iconic yellow colour and by the perfect sound it reproduces inside a vehicle. It is supported by a strong and super reliable rubber surround, whose exclusive profile has been optimised to provide lengthy travel, a top choice for your in-car audio system.

The aramid fibre cone inherits all of Focal’s unique know-how. Composed of an ultralight foam core, sandwiched between a thin layer of aramid fibre and a layer of fibreglass, it combines 3 key factors when it comes to acoustics: rigidity, lightness and damping, for sound that is as precise and dynamic as it can get.

The speaker drivers benefit from TMD (Tuned Mass Damper) technology, a patented innovation. This surround has a special profile, designed to better control the effect of resonance and reduce the distortion associated with deformations of the cone. The midranges are perfectly defined and very realistic.

The Radial VC cooling system for the speaker driver coil expels hot air from the coil towards the bottom of the motor through 6 holes. This improves control over the coil temperature, limiting the effects of heat compression and improving reliability. This improves the dynamics of the speaker driver and generates a powerful sound.

The progressive spider on the K2 Power speaker drivers is built around a progressive section to reproduce all the impact of the bass and increase the linearity, precision and dynamics of the sound.
