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.

To drive this single subwoofer, we recommend a mono amplifier rated between 225 and 450 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

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.
