Focal Utopia Be® 33 WX2
13" 4-ohm subwoofer
Our take on the Focal Utopia Be® 33 WX2 by Crutchfield's 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 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.

"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. This type of enclosure offers power efficiency and deep, loud bass frequencies. The recommend vented box volume for the Focal Utopia Be (13 WX2) is 1.236 cubic feet with a 3.9375" diameter x 11.811" long port; or 1.589 cubic feet with a 3.9375" diameter x 9.842" port.
