About the Focal Performance Sub P 25F

Bob Bihlmayer

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.

Impressive performance

Focal's Performance Sub P 25F 10" sub delivers performance beyond its size, using its flax cone, 2" voice coil and double magnets to handle up to 300 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 25 liters (0.88 ft³).

Ported Box Volume: Focal recommends a ported enclosure with a volume between 25 liters (0.88 ft³) and 35 liters (1.24 ft³) using a single port tube (size in the table below):

Q
What is a good sealed box size for these? Is the sound ordnance for 2 10's that gives .76 a good fit?

Yes that is exactly the one I would recommend for two of those 10" Focals. Here is a link https://bit.ly/2VHerhl

Q
I'm considering replacing my 2- 10" sub with a pair of these guys, with a 1200w JL HD amp, is this too much power for these ?

Thanks for your question. For information on selecting the best amp/sub combo I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system.
