What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Our take on the Focal Utopia Be® 13 WS

by Dominic Devito

Focal's top-of-the-line Utopia Be speakers exemplify Focal's dedication to musical perfection. The sound enthusiasts at Focal worked without constraints to develop what they consider to be the ultimate in speaker technology. Utopia Be subwoofers employ unique materials and unparalleled construction to add incomparable dynamics and natural sound to your system.

Focal's composite sandwich "W" cone features a layer of durable structural foam between two layers of precision-coated glass — the resulting membrane demonstrates exceptional agility, rigidity, and damping to produce realistic bass notes without distortion. A supple rubber surround maintains precise control over the cone, even during extreme excursion. A dense neodymium magnet, high-linearity voice coil, and zinc alloy basket give the sub rock-solid power and strength.

The compact Utopia Be 5" 13 WS subwoofer fits in places most other component subs can't, and you'll be impressed by its sound quality and bass impact. It handles up to 75 watts RMS and works best in small sealed enclosures. Utopia is defined as an "ideal place or state," and these hand-crafted Focal subs let you take your music to that level.

  • 5" 4-ohm subwoofer
  • "W" structured foam and glass composite sandwich cone with rubber surround
  • zamak (zinc alloy) basket
