Sonus faber Lumina I Bookshelf Loudspeakers (pair)

Compact 2-way bookshelf loudspeakers with a 29 mm DAD silk-dome tweeter, 120 mm midwoofer, and 84 dB sensitivity

The Sonus faber Lumina I combines exceptionally compact proportions with the natural, expressive sound that defines the Italian manufacturer's loudspeakers. As the smallest bookshelf model in the Lumina collection, it offers an elegant solution for smaller listening spaces while delivering the musical engagement and refinement associated with Sonus faber.

Its 2-way design combines a 29 mm DAD silk-dome tweeter with a 120 mm midwoofer in a compact, vented enclosure. With its carefully engineered crossover, signature Sonus faber materials, and versatile placement options, Lumina I is an excellent choice for sophisticated stereo and multichannel systems where space is at a premium.

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.

Compact Design, Engaging Sound

As the smallest bookshelf loudspeaker in the Lumina collection, Lumina I is designed to deliver a compelling musical presentation from an exceptionally compact enclosure. Its 120 mm midwoofer and carefully proportioned cabinet provide a balance of tonal accuracy, clarity, and dynamic responsiveness while retaining the clean lines and manageable dimensions that make bookshelf speakers so versatile.

The compact cabinet and front-firing bass-reflex port allow Lumina I to deliver an engaging listening experience without requiring a large listening space. It is equally at home in a dedicated stereo system, a desktop listening setup, or as part of a multichannel home theater.

Optimized Crossover for Natural Sound

The Lumina I features a carefully designed crossover network optimized for amplitude and phase response, supporting precise imaging and a coherent soundstage. Its crossover frequency of 2,000 Hz establishes a smooth transition between the tweeter and midwoofer, helping preserve the natural tonal balance and spatial presentation associated with Sonus faber loudspeakers.

The crossover incorporates specially designed Sonus faber capacitors and high-quality components, reflecting the company's attention to the interaction between drivers and crossover circuitry. This approach emphasizes clarity, tonal continuity, and the convincing reproduction of voices and acoustic 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 120 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 in Italy, the Lumina I combines the collection's minimalist rectangular cabinet with Sonus faber's signature use of natural materials. Its multilayer wood front baffle is available in Walnut or Wenge veneer with maple inlays, or a polished Piano Black lacquer finish.

The cabinet's sides and top are hand-covered in black leather, while chrome-finished rings around the drivers add a subtle visual accent. 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 exceptionally compact footprint, Lumina I is well suited to speaker stands, shelving, desktops, 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 84 dB, Lumina I is designed to partner with a capable integrated amplifier or separate amplification system.
