Sonus faber Serafino G2 - Wenge - Red - Graphite

Description

Intono Technology for the Midrange

At the heart of the vocal presentation lies Intono technology, a dedicated internal acoustic chamber for the midrange driver. Its structure reduces the internal acoustic pressure generated behind the driver cone — pressure typically responsible for the spurious distortions that contaminate the vocal range. The concrete result: a cleaner, more legible midrange with better articulation of human voices and acoustic instruments.

High-Frequency Resolution with the DAD Arrow Point Tweeter

High-frequency reproduction is handled by the DAD Arrow Point (Damped Apex Dome) tweeter, a 28 mm silk dome with a high-power neodymium magnet motor. Localized damping applied to the apex of the silk dome prevents the anti-phase behavior that typically affects soft domes at high excursion. This mechanical intervention extends the linear frequency response up to 35 kHz, producing a resolved, spacious, fatigue-free treble that integrates precisely with the midrange.

Dual 180 mm Woofers in the Stealth Ultraflex System

Low-frequency energy is channeled through the Stealth Ultraflex bass-reflex system, whose port profile is optimized to minimize audible turbulence at high excursion. The two 180 mm woofers have been enhanced for this second generation: new voice coil and new spider for greater air movement and improved extension. Measured result: bass extension down to 30 Hz with well-damped control, even on demanding musical passages.

Phase Coherent Level 3 Crossover with Jantzen Components

The crossover network is a Phase Coherent Level 3 — the most elaborate version of the Sonus faber topology, designed for strict phase alignment across the three ways. Components are selected from the high-end category: Jantzen inductors (Danish, an industry reference), hand-soldered capacitors, custom Clarity components. This combination preserves the purity of micro-details at realistic listening levels.

Acoustic Decoupling with the ZVT System

To ensure the mechanical energy of the drivers is transferred exclusively to the air and not to the floor, the cabinet is decoupled using the Zero Vibration Transmission (ZVT) system. The decoupling spikes isolate the loudspeaker from structural floor vibrations, preventing low-frequency feedback, tightening the bass response, and anchoring the soundstage with focused imaging.

Frequently Asked Questions

What does Intono technology bring to the midrange?

The internal acoustic chamber of the midrange driver, with Intono technology, reduces the internal acoustic pressure generated behind the cone during operation. This pressure is typically responsible for the spurious distortions that contaminate the vocal range. By tackling the problem mechanically rather than electronically, Intono preserves the natural speed and phase accuracy of human voices and acoustic instruments.

Do these speakers require a powerful amplifier?

The Serafino G2 has 90 dB SPL sensitivity and a 4 Ω nominal impedance. Sonus faber recommends a power range of 50 to 300 W per channel. A high-current amplifier from 50 W is a good fit; the speaker's potential is fully expressed with high-end power blocks or medium-power tube amplifiers (50 to 150 W). The four binding posts (Mid-Hi and Low) also allow bi-wiring or bi-amplification.

How should the Serafino G2 be positioned in a room?

To maximize soundstage depth, pull the speakers away from the front and side walls, which lets the Stealth Ultraflex system couple with the room without the bass becoming overpowering. A slight angle toward the primary listening position will focus the high-frequency energy from the DAD tweeter. The included ZVT spikes must be installed and leveled to ensure proper mechanical decoupling.
