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 25A4 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 200 watts RMS. Install this sub in a sealed box for tight, punchy bass, or in a ported enclosure for a little more boom.

Focal 25A4

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.

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 25A4 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 15 liters (0.53 cubic feet) and 25 liters (0.88 cubic feet).

Ported Box Volume: FOCAL recommends a ported enclosure with a volume between 20 liters (0.71 cubic feet) and 35 liters (1.24 cubic feet) using a single 3-1/2" diameter 13-3/4" long port tube.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
I love the clean, vivid sound of Focal components and wanted a cleaner low end to replace the 15" P3 Rockford sub which worked great on an EQ. Aaron had good advice. Thanks. [ chris  Jul 11, 2018 ]
