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.

Our take on the Focal SB 30 A1

by Dominic Devito

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.

The enclosure is made of 5/8" MDF and features internal damping material for added rigidity and less vibration noise. The enclosure also features a removable metal grille to protect the woofer's cone. In addition, the subwoofer enclosure utilizes nickel-plated spring-post terminals for easy connection of your speaker wire (up to 10AWG). The FOCAL SB30A1 presents a 4-ohm load at its speaker terminals. The subwoofer enclosure features four rubber feet and comes with a mounting kit which consists of two nylon straps, four metal brackets and eight screws to secure the enclosure in your vehicle.

The woofer also features a butyl rubber surround to promote long life and durability. The Access 30A1 woofer features a 4-layer, 2" voice-coil for higher power handling capabilities up to 250 watt (RMS) and 500 watt (Peak). The Access 30A1's voice-coil cooling system provides optimized reliability with no dynamic compression.
