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 KXE has impressive power handling

The 25 KXE subwoofer is a compact 10” (25cm) woofer. Its high-power handling and reliability are impressive. Like all the kits from the K2 Power line, the SUB 25 KXE features the iconic yellow K2 cone. A Focal innovation, the cone is supported by a strong, highly reliable rubber surround, whose exclusive profile has been optimised to enable very long travel. It is the source of perfect sound reproduction on board.

At Focal, every detail counts. Also, the aluminium chassis is a key player in quality sound reproduction. Rigid, non-magnetic, and specially designed for K2, it improves the excursion of the coil and allows the subwoofer to deliver sustained, striking, dynamic bass.

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.
