Our take on the Focal Performance SUB P 25

by Bob Bihlmayer

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Pure bass power

Focal's Performance Series subwoofers deliver pure bass power so your music always hits strong and true. This Performance Series SUB P 25 10" sub features a light, tough poly cone and a self-regulating cooling system, so it'll perform reliably even when you're pushing it hard. A butyl rubber surround adds to the sub's strength, durability, and accuracy.

Performance and versatility

With heavy ferrite magnets and a 4-layer voice coil, it's no surprise this sub handles plenty of real world power — up to 200 watts RMS. The 90 dB sensitivity rating means your amp won't have to work as hard to drive this sub, so you'll get maximum wallop per watt. You can install this sub in a sealed box for tight, punchy bass, or in a ported enclosure for a little more boom.

To drive this single subwoofer, we recommend a mono amplifier rated between 150 and 300 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Focal Sub P25

Written By 71Torino, Baltimore, MD on Wednesday, October 15, 2014
Crutchfield Customer Review (What's this?)
Easy cross-fit in my JBL sub box, both 10" subs came out of the box and were installed with no problems whatsoever. I had to port the box and Crutchfield sent me the information and details I needed to get it done. Excellent customer service too. The sound through my Zapco ST5D is phenomenal. These Focal's handle it!
