E 25 KX



The E 25 KX is a very compact 10" (25cm) subwoofer. It offers very high power handling and exceptional reliability. Available in sealed box or bass-reflex type enclosures, this subwoofer has an astonishing SPL of 84.5dB considering its compact design!

It features a yellow Kevlar® cone which is light, rigid and has excellent damping to provide extremely dynamic bass.

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 aluminum 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 speaker drivers used for the K2Power 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! The K2Power 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 K2Power cone combines three key factors of quality acoustics:
• Rigidity
• Lightness
• Damping, for precise and dynamic sound.

“Radial VC” cooling


The new Radial VC cooling system for speaker driver voice coils expels hot air from the voice coil towards the bottom of the magnet through 6 holes. This improves control over the voice coil temperature, limiting the effects of thermal compression and improving reliability. This significantly increases the efficiency of the speaker driver. It also improves dynamics and produces a more powerful sound.
