Focal designs their Access 1 Series loaded sub enclosures to satisfy your appetite for bass. Each enclosure uses 5/8"-thick medium-density fiberboard with internal damping for dynamic bass without shakes and rattles. The advanced flared port design allows Focal to make the box smaller, yet still able to deliver deep, accurate bass that won't flag or falter.
The SB 30 A1 ported box packs the bass firepower of an Access 12" 30 A1 subwoofer, which handles up to 250 watts RMS for strong performance. Focal assembles these boxes by hand so you know they'll provide reliable thump from the first note. Pair this handsome package with a compatible amp and some wiring, then find out how a good sub system can transform your commute.
