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 massive, multi-element magnet, high-linearity two-layer voice coil, and zinc alloy basket give the sub rock-solid power and strength.

The Utopia Be 33 WX2 13" subwoofer represents the pinnacle of Focal's pursuit of perfect-sounding, full-bodied bass. It handles up to 400 watts RMS and works in small or medium vented boxes. Utopia is defined as an "ideal place or state," and these hand-crafted Focal subs let you take your music to that level.

To drive this single subwoofer, we recommend a mono amplifier rated between 300 and 600 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

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.

I am writing this review because of the lack of reviews of focal subs on the internet. Nothing I have come across justifies what I have just recently put in my GMC acadia suv. Okay so I had the box built to specs with minor alteration to the port. I mathematicaly made my port square with an identical volume. For the best sound be as precise as possible. Okay so I put it in my car and my installer said for such an expensive sub I'm very skeptical. His reaction was, instead of 5 min throw the sub in and go, turned to an 70 minute listening session. We both ageed it doesn't get any better. Loud, crisp, precise, musical, unbelivable bass!!! Best sub I've ever heard and for the record louder then my 10w7 JL HO box.

Pros: strong cone, no distortion, flat bass response, precise, loud, crisp, moves you, musical ...........

"W" Composite Sandwich Cone Woofer: The Focal Utopia Be (33 WX2) 13" subwoofer features a "W" composite sandwich cone woofer. The rigidity offered by the glass layers delivers extreme linearity over a wide frequency range without and low frequency distortion. The structural foam central core's lightness allows optimal acceleration, without delay, while damping derived from the "W" material produces a neutral, coloration free sound.

Rubber Surround: The FOCAL Utopia Be 33 WX2 features a long-throw rubber surround for long excursion, deep bass (27-350Hz), and added durability to promote long life.

2-Layer Voice Coil: The FOCAL Utopia Be 33 WX2 features a 2-layer voice-coil for high power handling and bass without distortion.

Multi-Ferrite Magnets: The Utopia Be 33 WX2 woofer utilizes six double-stacked Ferrite magnets (12 total) to create a powerful magnetic field to help suppress compression and give better power handling. This Multi-Ferrite motor assembly allows for greater efficiency (92db), higher power handling capabilities, and natural cooling of the woofer's voice coil.

Die Cast (Zamak) Vented Basket: The FOCAL Utopia Be 33 WX2 features a vented die-cast Zamak basket which is a rigid, non-magnetic, and non-resonant frame that provides a strong, reliable structure for the woofer. The vented basket provides a self-regulated coil cooling system which allows air to flow freely preventing heat build-up and optimized reliability and performance consistency.

5-Way Binding Posts: The FOCAL 13" woofer is equipped with a pair of gold-plated 5-way binding post speaker terminals for easy connection up to 10AWG wire.

Foam Gasket: The Utopia Be 33 WX2 comes supplied with a self-adhesive foam gasket mounting-ring for better chassis damping and to prevent air leakage.

Removable Cloth Cover: The Utopia Be 33 WX2 woofer comes with a cloth cover to protect the magnet from scratches or smudging during transport, handling, and installation. The cloth cover should be removed once the woofer is installed. The cloth cover is not designed to be placed on the woofer after it has been installed.

Ported Box Enclosure: The Focal Utopia Be (13 WX2) 13" subwoofer has been optimized to work in a bass-reflex (ported) enclosure.
