Sonus faber Lumina II Amator Bookshelf Loudspeakers (pair)

2-way bookshelf loudspeakers with a 29 mm DAD silk-dome tweeter, 150 mm midwoofer, upgraded crossover, and 86 dB sensitivity

The Sonus faber Lumina II Amator elevates the compact Lumina II bookshelf loudspeaker with a refined crossover design and luxurious finishes. Drawing on technologies developed for Sonus faber's acclaimed Homage collection, this special edition delivers greater resolution, improved spatial coherence, and the natural, expressive sound that defines the Italian manufacturer's loudspeakers.

The Amator designation has traditionally been reserved for special Sonus faber models, and the Lumina II Amator honors that heritage with meaningful engineering improvements and distinctive craftsmanship. Its 2-way design combines a 29 mm DAD silk-dome tweeter with a 150 mm midwoofer in a compact, vented enclosure, making it an excellent choice for smaller listening spaces or sophisticated stereo and multichannel systems.

About the Lumina Collection

The Lumina collection brings the distinctive sound and design philosophy of Sonus faber to a more accessible range of loudspeakers. Designed and made in Italy, the series draws on technologies developed for the company's higher-end models, combining carefully selected drivers, sophisticated crossover designs, and natural materials to deliver the musical warmth, tonal richness, and lifelike presentation for which Sonus faber is known.

The name Lumina reflects three defining elements: LU for luxury, MI for minimalist design, and NA for natural sound. With clean, contemporary lines, real-wood front baffles, and hand-finished leather surfaces, the collection distills traditional Italian craftsmanship into a versatile family of loudspeakers suited to both dedicated stereo systems and multichannel home theaters.

Amator Heritage and Homage-Inspired Engineering

For Sonus faber, the Amator name signifies something special. Previous Amator models have combined the company's most distinctive design elements with carefully considered technical refinements, and the Lumina II Amator continues that tradition.

Its most significant improvement is a redesigned crossover network informed by the development of the fifth-generation Homage collection, including the Amati G5 and Guarneri G5. The revised circuitry incorporates Sonus faber's IFF (Interactive Fusion Filtering) approach and phase-coherent design philosophy, with the goal of delivering greater resolution, more precise imaging, and a convincing three-dimensional soundstage.

Upgraded Crossover for Greater Coherence

The Lumina II Amator's crossover frequency has been raised from 1,800 Hz in the standard Lumina II to 2,600 Hz. This substantial revision changes the operating ranges of the tweeter and midwoofer, allowing the drivers to work together with improved phase and amplitude behavior.

Drawing on solutions developed for Sonus faber's higher-end loudspeakers, the crossover uses carefully selected hi-fi components and an optimized filter design. These improvements are intended to preserve the tonal continuity of the original Lumina II while enhancing clarity, spatial definition, and the natural presentation of voices and instruments.

Signature DAD Tweeter and Natural-Fiber Midwoofer

High frequencies are reproduced by Sonus faber's 29 mm DAD (Damped Apex Dome) tweeter, also used in the Sonetto collection. Its hand-coated Kurt Müller silk diaphragm incorporates damping technology that controls the behavior of the dome apex, reducing unwanted resonance and supporting smooth, extended treble reproduction. Viscoelastic decoupling from the front baffle further helps isolate the tweeter from cabinet vibrations.

The 150 mm midwoofer uses a diaphragm composed of cellulose pulp blended with natural fibers, supported by a custom-designed basket. This combination emphasizes low coloration and natural tonal reproduction while providing the dynamic range needed for both midrange detail and bass performance. The front-ported bass-reflex enclosure extends low-frequency output while offering flexibility in speaker placement.

Distinctive Italian Craftsmanship

Designed and manufactured at Sonus faber's facility in Vicenza, Italy, the Lumina II Amator retains the collection's minimalist rectangular cabinet while introducing a more elaborate treatment of its real-wood front baffle. The woodgrain veneer is arranged at a distinctive 45-degree angle, creating a striking visual pattern that highlights the natural character of the material.

High-gloss Walnut, Wenge, and Red finishes are paired with hand-applied black leather on the cabinet's sides and top. Chrome-finished rings around the drivers add a subtle accent, bringing together traditional Sonus faber materials and a clean, contemporary aesthetic. The result is a compact loudspeaker that reflects the company's longstanding attention to both acoustic engineering and visual design.

Versatile Placement and System Integration

With its compact footprint, Lumina II Amator is well suited to speaker stands, shelving, or other spaces where a larger loudspeaker would be impractical. Its front-firing reflex port provides additional placement flexibility, while rubber isolation pads help decouple the cabinet from the supporting surface.

Dual pairs of binding posts provide separate connections for the tweeter and midwoofer sections, allowing conventional single-wiring, bi-wiring, or bi-amping. With a nominal impedance of 4 Ω and sensitivity of 86 dB, Lumina II Amator is designed to partner with a capable integrated amplifier or separate amplification system.
