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.
To drive this single subwoofer, we recommend a mono amplifier rated between 55 and 110 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
