Our take on the Focal SB 30 A1

by Dominic Devito
Focal

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

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.
