Focal P25FSE - 10" 25cm 560 Watts 4 Ohm Flax Cone Slim Shallow Car Subwoofer
 FLAX TO THE MAX
 If you've heard Focal speakers, then you know that their reputation for quality is well-deserved. Focal's designers never hesitate to think outside the box when it comes to speaker innovation. To create their Flax Evo Series speakers and subs, for example, they spent five years developing a super-lightweight, extra-rigid cone material made from a layer of flax fibers sandwiched between two layers of glass fibers. You get the warmth of natural fiber combined with the supreme accuracy of a more rigid cone material.
 SMALL SIZE, BIG SOUND
 Built at Focal's workshop in France, the P 20 FSE 8" sub delivers performance beyond its size, using superior materials and construction to handle up to 200 watts RMS. At only 3" deep, its shallow-mount design allows it to fit in a compact sealed enclosure, so it's easier to fit in a smaller vehicle. If you're putting together a system, make sure to take a look at Focal's component speaker systems that feature the same "Flax Sandwich" cones.
