About the brand

Sonus faber represents Italian excellence in the world of high-end hi-fi speakers, founded in 1983 in Arcugnano, in the province of Vicenza, by Franco Serblin. The Veneto-based brand positions itself in the luxury segment of the international audiophile market, combining traditional Italian craftsmanship and technological innovation to create speakers that are true works of sonic art.
Sonus faber's philosophy is based on the pursuit of a natural and engaging sound, capable of conveying the warmth and emotion of live music, respecting the timbre of the instruments and the spatiality of the original musical event. Franco Serblin gave Sonus faber loudspeakers the distinctive curved, wood-clad cabinets that have defined their aesthetic identity, and several of the brand's models bear the names of great Italian luthiers. The company is still headquartered in Arcugnano. Since 2007, Sonus faber has been part of an industrial group that since 2012 has also included McIntosh (now McIntosh Group).
Sonus faber's distinctive technologies include the Stealth Ultraflex reflex port, which reduces harmonic distortion and improves low-end extension, and the Paracross crossover topology, which makes the crossover less sensitive to radio frequency interference, improving transient response. The tweeters use silk domes with the DAD (Damped Apex Dome) damping system, while the midrange drivers of various series use cones made of cellulose pulp mixed with other natural fibers, resulting in a particularly natural timbre.
The Sonus faber range is divided into several collections that cover a broad spectrum of audiophile needs: floorstanding and bookshelf speakers, active wireless speakers, subwoofers from the Gravis collection, in-wall speakers for dedicated installations and outdoor speakers.
The collection References represents the brand's production pinnacle, with models such as the Aida. The collection Homage, dedicated to the great Italian luthiers, includes the flagship Amati, the Guarneri and the Serafino. The line Olympica Nova expresses the natural sound signature of the brand, the collection Heritage inspired by the first Sonus faber models, the collection Sonetto, now in its second generation, combines tradition and new technologies, while the series Lumina Hair Care offers compact speakers with a minimalist design. The collection Palladium It is the first Sonus faber line of in-wall speakers for custom installations.
Sonus faber's target audience includes discerning audiophiles, collectors, and music enthusiasts seeking speakers that combine reference-level performance with exclusive design. The brand appeals to those who see speakers not just as musical reproduction tools but as artistically valuable furnishings.

How to choose and adjust a subwoofer: a practical guide

A well-integrated subwoofer can't be heard: you only notice it's there when you turn it off and the music loses body, space, and scale. A poorly adjusted one, however, makes itself immediately noticeable, with a bloated bass that comes from one corner...

When You Need a Subwoofer (and When You Don't)

A subwoofer's job is to reproduce the lowest octave of the spectrum, which many speakers, especially compact ones, only partially reproduce. In home theaters, it's almost indispensable: soundtracks feature a dedicated low-frequency effects channel, the famous ".1," designed specifically for a separate speaker.
