Dream speakers

Perfect sound. Discreet style. Premium construction. These are the standards that define Focal – and that make listening to Focal speakers an absolute pleasure. The Access line offers a marriage of performance and affordability, allowing you to experience the best in sound with a guilt-free conscience.

Feel the bass

Bass gives your music fullness and texture. If you shortchange the bass, you're not hearing your music the way it's meant to be heard. This Focal Access Series 30A4 subwoofer uses an all-weather DFS (dual fiberglass structure) cone to deliver that depth of character you may be missing from your system. The cone's butyl rubber surround helps to ensure excellent strength, durability, and musical accuracy.

A unique ventilation system keeps the voice coil cool, allowing this sub to handle up to 250 watts RMS. Install this sub in a sealed box for tight, punchy bass, or in a ported enclosure for a little more boom.

Focal 30A4

To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 375 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

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.

Features

Cone Material: The Dual Fiberglass Structure Membrane (DFS) is a light, rigid, woven glass fiber woofer cone. The butyl rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.

Spring-Posts: The 30A4 uses spring-post speaker terminals for easy connection of single banana plugs, pin connectors, 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 20 liters (0.71 cubic feet) and 30 liters (1.06 cubic feet).

Ported Box Volume: FOCAL recommends a ported enclosure with a volume between 25 liters (0.88 cubic feet) and 35 liters (1.24 cubic feet) using a single 3-1/2" diameter 13-3/4" long port tube.
