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.
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.
