Focal

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.

Our take on the Focal Performance Sub P 30 DB

by Buck Pomerantz

Focal's Performance Series subwoofers deliver pure bass power so your music always hits strong and true. This Performance 12" sub features a light, tough poly cone and a self-regulating cooling system, so it'll perform reliably. A butyl rubber surround adds to the sub's strength, durability, and accuracy.

Performance and versatility
With heavy ferrite magnets and 4-layer voice coils, it's no surprise this sub handles plenty of power — up to 300 watts RMS. The good sensitivity rating means your amp won't have to work so hard to drive this sub, so you'll get maximum wallop per watt. The dual 4-ohm voice coils allow you to wire the sub for either 2-ohm or 8-ohm impedance, and you'll appreciate that versatility as your system grows and changes. You can install this sub in a sealed box for tight, punchy bass, or in a ported enclosure for a little more boom.

    Features

    Materials: The FOCAL P 30 DB features a polypropylene cone and butyl rubber surround to withstand the harsh automotive environment.

    Dual 4Ω Voice Coils: The dual 4Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 2Ω load, when wired in series the woofer presents an 8Ω load.

    Spring-Posts: The P 30 DB uses spring-post speaker terminals for 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 25 liters (0.88 cubic feet) and 45 liters (1.59 cubic feet).

    Ported Box Volume: FOCAL recommends a ported enclosure with a volume between 35 liters (1.24 cubic feet) and 80 liters (2.82 cubic feet) using a single port tube (size in the table below):
