About the Focal P 20FE

Flax to the max
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 20FE 8" sub delivers performance way beyond its size, using superior materials and construction to handle up to 250 watts RMS. It works equally well in compact sealed or ported enclosures, so it's a great candidate for great bass 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.

Features
Cone: The woofer cone is a sandwich design, with a flax center between two glass layers. This combination of materials results in a neutral sound without coloration.
Surround: The rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.
Spring-Posts: The spring-post speaker terminals offer easy connection of single banana plugs or bare wire up to 10 gauge.
Rubber Gasket: The gasket/mounting-ring ensures better chassis damping and prevents air leakage. The rubber gasket is removable.
Sealed Box Volume: Focal recommends a sealed enclosure with a volume between 10 liters (0.35 ft³) and 15 liters (0.53 ft³).
Ported Box Volume: Focal recommends a ported enclosure with a volume between 10 liters (0.35 ft³) and 20 liters (0.71 ft³) using a single port tube (size in the table below):

I am running 3 of these under the back seat of an 01 Colorado with an FPX 1000.1 and they pound. Nobody believes it until they see it. The sound quality is ridiculous!
