The Sonus faber Concertino is a compact, high-end bookshelf (standmount) loudspeaker that sits at the heart of Sonus faber’s heritage. First introduced in the 1990s and now in its latest G4 generation, it represents a blend of classic Italian craftsmanship and modern acoustic engineering.

It is a two-way passive speaker, meaning it needs an external amplifier. Inside, it typically uses a mid-woofer (around 5 inches) and a silk-dome tweeter, designed to produce a natural, balanced sound across the frequency range. The sound signature is very much in line with Sonus faber’s philosophy: warm, detailed, and musical rather than aggressively analytical.

One of the defining features of the Concertino is its design and materials. The cabinet keeps the brand’s iconic curved, lute-inspired shape and uses premium materials like solid walnut wood, leather (or plant-based alternatives), cork damping, and brass accents. This isn’t just aesthetic—these materials are chosen to improve resonance control and overall sound quality.

Sonically, the Concertino is known for excellent imaging, natural vocals, and refined treble, with a more intimate presentation rather than huge room-filling bass. It performs best in a dedicated listening setup, where you sit in front of the speakers and focus on detail and realism.

In terms of positioning, the modern Concertino (G4) sits in the premium audiophile category, typically around €4,000–€5,000 per pair, making it a serious enthusiast product rather than an entry-level speaker.

Overall, the Sonus faber Concertino is less about convenience and more about pure listening pleasure—a small speaker that prioritizes musicality, craftsmanship, and emotional sound over sheer power or features.
