About the Focal Performance Sub P 20F

The flax connection

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 Performance 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.

You won't believe it's an 8" sub.

An 8" sub that thinks it's a giant

Focal's Performance Sub P 20F 8" sub delivers performance way beyond its size, using its 1-1/2" voice coil and double magnets 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 the Focal component speaker systems that feature the same "Flax Sandwich" cones.

Product Research

Features

Cone: The woofer cone is a sandwich design, with a 0.6mm flax center between two 0.2mm 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):

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
Sound quality and reputation [ CHARLES  Jun 12, 2018 ]
A
Best option for my 8" stock location. I think it will turn out great. My amplifier will power it great and if I put in a second it will still work with the same amp. [ BRIAN  Dec 06, 2017 ]
A
because I have focal door speakers [ THOMAS E  Jan 18, 2016 ]

2 questions already asked

Q
can these be used for free air woofers in the back deck?
[ Tim  Feb 09, 2018 ]
1 answer
A
There are sizes for both sealed and vented woofer boxes. I cannot be sure, but if your trunk is sealed and/or insulated it may work. The woofers sound excellent in a sealed woofer box.
[ James  Feb 09, 2018 ]
Q
Are the recommended enclosure volumes taking into account the speaker volume?
[ Jorge E  May 18, 2016 ]
1 answer
A
Yes, absolutely. There's a range for each type as well: sealed box volume: 0.35-0.53 cubic feet ported box volume: 0.35-0.71 cubic feet So, as long as the airspace falls within the recommended range for the specific enclosure type, you'll be good to go. I hope that helps. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5
