Wilson Benesch Fibonacci Series Horizon Loudspeaker (pair)
HORIZON: boundless innovation in sound
Introducing Horizon, the latest innovation in Wilson Benesch’s award-winning Fibonacci Series. Engineered and crafted in Sheffield, England, Horizon distills three decades of acoustic innovation into a compact floorstanding loudspeaker, delivering breathtaking sound, precision engineering, and cutting-edge materials science.
At the core of Horizon’s revolutionary performance is Wilson Benesch’s bio-based A.C.T. 3zero Monocoque enclosure, a breakthrough in composite technology that ensures acoustic purity by all but eliminating enclosure resonance. This advanced structure allows the music—not the loudspeaker—to take centre stage.
Horizon is powered by proprietary Tactic 3.0 Drive Units and the Fibonacci Tweeter, developed and hand-built entirely in-house. The Tactic 3.0 midrange and bass drivers work in harmony with the enclosure, while the Fibonacci Tweeter, featuring a silk dome reinforced with a carbon fibre halo, delivers natural non-sibilant highs with exceptional clarity and precision, extending up to 30kHz.
Wilson Benesch’s legacy in composite materials dates back to 1992, pioneering carbon fibre enclosures with the iconic A.C.T. One. This expertise evolved into the A.C.T. Monocoque in 2001, integrating aerospace-grade Vacuum Resin Transfer Moulding (VRTM) technology for unrivalled performance. Furthering this innovation, Wilson Benesch joined The SSUCHY Project, a €7.4-million European R&D initiative, to develop the world’s first bio-based composite loudspeaker enclosure.
Horizon embodies this relentless pursuit of perfection. Its curved geometric form, inspired by the Fibonacci Series, is visually striking and acoustically optimised, setting a new industry benchmark for compact floorstanding loudspeakers.
From enclosure to drive units, every element is meticulously designed, manufactured, and assembled in-house, ensuring absolute precision and uncompromised quality. The result is an immersive soundstage with breathtaking detail, dynamic range, and authenticity—redefining high-fidelity listening in this product class.
Horizon is not just a loudspeaker. It is the pinnacle of British audio engineering, artistry, and acoustic excellence.
DESIGN
The Reference in High-Frequency Reproduction – Fibonacci Silk-Carbon Hybrid Tweeter
The second-generation Wilson Benesch tweeter sets a new benchmark in high-frequency sound, advancing beyond the original Semisphere design through iterative research and cutting-edge manufacturing.
Enabled by in-house additive manufacturing, the tweeter features the distinctive Fibonacci Element—an acoustically transparent carbon fibre-nylon faceplate that delivers wide dispersion and a smooth frequency response. It’s mechanically decoupled to reduce resonance and preserve fine detail.
At the rear, the Labyrinth Enclosure—a 3D-printed, geometrically complex backplate—traps and dissipates unwanted energy, ensuring exceptional clarity. A unique open motor design using rare earth magnets improves thermal management, maintaining performance under pressure. Every element reflects Wilson Benesch’s commitment to innovation, precision, and sonic purity.
Tactic 3.0 Drive Unit – A Masterclass in Precision Engineering
Wilson Benesch’s Tactic 3.0 is the result of decades of in-house R&D—precision-engineered to deliver unmatched audio performance. Unlike manufacturers using off-the-shelf components, every element of the Tactic 3.0 has been designed and manufactured by Wilson Benesch, ensuring total control over quality and integration.
From a uniquely optimised basket and dual motor plates for superior efficiency and dynamics, to individually tailored diaphragms and voice coils, every detail enhances clarity, speed, and control. Advanced magnetic field optimisation—developed with Sheffield Hallam University—and the 3D-printed Fibonacci Element further reduce distortion and preserve detail.
The result? A drive unit that responds with precision, reproducing sound that is natural, dynamic, and immersive.
Laminar Flow Guide - Where Design Meets Acoustic Precision
The Wilson Benesch Horizon is a loudspeaker designed to strike the perfect balance between performance and aesthetics. Its refined proportions and sculptural form allow it to integrate beautifully into both compact and open-plan spaces, with every curve engineered for optimal acoustic performance.
At the heart of its innovation is the Laminar Flow Guide—3D-printed in-house to regulate airflow and reduce turbulence. This minimises distortion and improves clarity, especially in rooms where placement near walls is unavoidable.
Engineered for versatility, the Horizon adapts effortlessly to different environments, maintaining exceptional detail and musicality throughout.
A.C.T. 3zero Monocoque – The Pinnacle of Loudspeaker Enclosure Innovation
At the core of the Wilson Benesch Horizon is the A.C.T. 3zero Monocoque—a revolutionary enclosure developed through the EU-funded SSUCHY project, blending cutting-edge material science with sustainable, bio-based composites.
Unlike traditional wooden cabinets, the A.C.T. 3zero delivers exceptional stiffness and damping in a thin-walled form, maximising internal volume for deep, controlled bass—without increasing the speaker’s size. Its curved, compact design also minimises resonance and room reflections, preserving the natural purity of the music.
Engineered to disappear acoustically within the room, the Horizon offers a truly immersive, lifelike listening experience.
