Product Information

Sub P 25 F Expert 10" 4-Ohm Flax Cone Subwoofer

FLAX CONE / 10″ Subwoofer

P25F is a 25cm (10″) subwoofer designed for a 18,4-liter- closed cabinet or a 25-liter- bass-reflex one. It is equipped with a very rigid Flax cone of 320 gr/m² which guarantees deep, powerful and linear bass. Its power is 300 Watts RMS and its frequency response goes from 33 to 500Hz. P25F Flax subwoofer represent a good compromise between bass pleasure and cabinet volume. The reference in the bass world!

The three Flax subwoofers consist of straightforward 4-Ohm voice coils which are perfectly suited for small enclosures (closed or bass-reflex). Several innovations raise their performance to an even higher level. Each model of subwoofer has a dual magnet, offering improved linearity and ensuring optimal magnetic power delivered to the voice coil, which features a new cooling system. Glass fiber has been used for the mounting of the voice coil, making it more robust while protecting the cone from the heat emitted. Last but not least, the new fixings connecting the cone to the voice coil and the spider to the basket improve reliability for extreme use (very high excursion).


  • “Dual Magnet” for more power
  • FLAX® technology for an exclusive cone
  • 14mm Xmax
  • High rigidity for deep and controlled bass
  • Improved excursion thanks to the new suspension
  • Optimized cooling of the voice coil
  • The best compromise for a small seal enclosure volume using (0.35 Cu ft – 10L)

The Flax Collection from Focal

When the flax-series was introduced to the car audio community, it showed how creative Focal can be. The SUB P 25F 10” flax car subwoofer not only sounds great, it also contains some prized Focal technologies and innovations that have served the French manufacturer so well over the years. The depth and clarity you receive from this Focal subwoofer is quite amazing. We’re sure you’ll enjoy it as much as we have.

Flax Woofer Cones

In Focal’s quest to find a lower-cost solution to the aramid fiber woofers found in the E 25 KX, they found flax. Flax is a naturally-occurring hollow-tubed material that is exceptionally strong and lightweight. The flax woofer cone is sandwiched between a pair of ultra-thin glass fiber sheets to help improve rigidity and performance. You’ll enjoy clean, uncolored sound from these ground-breaking subwoofers.

Allow Us To Suggest…

To properly power this subwoofer (assuming you are using only a single SUB P 25F subwoofer in your setup), we would recommend a single-channel (or monoblock) subwoofer amplifier that is stable at 4 ohms. Ideally, the power output of this car amplifier at 4 ohms would be around 400 watts.
