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.

Product Research

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.

Q
What amp would you recommend for two Focal 30A4 subs?
[ Young  Sep 06, 2019 ]
1 answer
A
Thanks for your question. For information on selecting the best amp for your subs 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 between the amp models and help you make the best choice for your system.

Q
Will the crunch two channel 1000.2 work with a single 12" focal 30a4 subwoofer?
[ David  Mar 07, 2019 ]
1 answer
A
According to the specs on the Crunch website that amp does 1000 watts at 4 ohms. That would way more than you need for one of those Focal subs. I would recommend this Alpine mono amp which pushes 300 watts at 4 ohms: https://bit.ly/2HtbUjn
