Sonetto III
A Harmony of Power and Elegance
The most compact floor-standing loudspeaker in the Sonetto G2 Collection, Sonetto III packs impressive power.

A Sound That Surprises
With its slender figure and exceptional power, Sonetto III combines design and innovation. A sophisticated 2.5-way system showcases the new flower-patterned suspension mid-woofer, meticulously designed by the Sonus faber DesignLab in Italy. This development process ensures that every aspect of the speaker's performance is carefully honed to deliver an unparalleled listening experience.
Deceptively Slim, Impressively Strong
Looks can be deceiving. Despite its slim dimensions, Sonetto III has the commanding presence of a much larger speaker, thanks to advanced technologies and design solutions. Its exquisite aesthetic appeal has been enhanced with a new concrete base, designed for improved structural integrity and effortless installation.

Organic Basket
Designed and developed in Sonus faber laboratories, the die cast baskets have been designed from scratch specifically for this collection.

Classic Design
The lute shape that characterises many Sonus faber models has been redesigned to ensure the delivery of the perfect control over internal resonances.

Slender Yet Mighty
Sonetto brings together Sonus faber’s core design principles in an elegant silhouette.

The Voice of Sonus faber
The distinctive flower design of the midwoofer rubber suspension, working together with the Damped Apex Dome (DAD) soft dome tweeter, defines the iconic "Voice of Sonus faber." Inspired by the power of nature, Sonetto III delivers pure, high-fidelity audio reproduction through our signature Natural Sound.

Size-Defying Sound
Concrete Base
With the introduction of a new concrete base, the Sonetto G2 series not only enhances the stability of its speakers but also reinforces their structural integrity. This innovative addition provides a solid foundation that minimises vibrations and ensures optimal performance, particularly in demanding listening environments.

Binding Post Cover
The round binding post cover, adorned with the Sonus faber logo and available on all Sonetto G2 models – except Sonetto Wall - serves both a functional and decorative purpose. Designed specifically for bi-wiring binding posts, the cover ensures the integrity of the connections while adding a touch of refinement to the rear panel of the speakers.

Phase Coherent
The Phase Coherent Crossover design philosophy implemented in the Sonetto G2 Collection ensures precise synchronisation of the drivers' phase rotations, striving for maximum parallelism. This meticulous alignment results in an immersive soundstage that is incredibly defined and palpable, allowing audiophiles to experience music with a heightened sense of realism.
