Everything you need to know about the product
Experience exceptional bass clarity and power with the FOCAL SUB 25 KXE, a premium 10-inch subwoofer from Focal's acclaimed K2 Power series. Engineered and handcrafted in France, this subwoofer embodies Focal's signature performance, combining dynamic sound reproduction with superior durability.
Its aramid fibre K2 cone, renowned for its stiffness and responsiveness, delivers high-output bass with precision and control. Whether you're designing a custom audio system or upgrading factory sound, the SUB 25 KXE ensures tight low-end impact, deep frequencies, and excellent sound dispersion in a compact size.

The diaphragm is the key component of a loudspeaker and sits at the heart of Focal's acoustic engineers' research. Shape and materials are essential for high-fidelity reproduction. In 1986, Focal's teams unveiled an aramid fibre sandwich membrane, recognisable by its unique yellow colour. It has been extensively renewed over the years while retaining the characteristics that made it such a success. Today, it consists of an ultra-light foam core sandwiched between a layer of aramid fibre and a layer of glass fibre — combining the three key factors of a loudspeaker membrane: rigidity, lightness, and damping, for a precise, dynamic, and uncoloured sound.
While Focal's engineers are experts in the development of exclusive diaphragms, they also innovate in all the components that make up their loudspeakers, including the surround that connects the diaphragm to the frame. Introduced in 2015, Tuned Mass Damper (TMD) technology with harmonic damping consists of the addition of finely positioned toroidal weights to stabilise the surround for even greater sonic neutrality. This technology enhances the midrange and addresses the erratic behaviour of the surround between 1 kHz and 2 kHz.
Whether you're aiming for tight musical bass or heavy low-end pressure, the SUB 25 KXE delivers professional-grade sound performance in a compact, rugged housing. This subwoofer is the perfect choice for a high-end car audio upgrade, giving you maximum performance without compromise.

A deep dive into our industry-leading technology and high-performance standards.
The K2 cone is an ultra-light foam core sandwiched between aramid fibre and glass fibre layers, combining rigidity, lightness, and damping for precise, dynamic, and uncoloured sound.
Tuned Mass Damper (TMD) technology uses finely positioned toroidal weights on the surround to stabilise it and eliminate erratic vibrations, improving sonic neutrality — particularly between 1 kHz and 2 kHz.
It suits both custom sealed and ported (bass reflex) enclosures, and is particularly popular in high-SPL car audio builds.
Yes — the SUB 25 KXE is engineered and handcrafted in France as part of Focal's acclaimed K2 Power series.
