Sonus faber Lumina III Floorstanding Loudspeakers (pair)

Compact 3-way floorstanding loudspeakers with a 29 mm DAD silk-dome tweeter, 150 mm midrange driver, dual 150 mm woofers, and 89 dB sensitivity

The Sonus faber Lumina III brings the Italian manufacturer's signature combination of natural sound, elegant materials, and refined craftsmanship to a compact floorstanding design. Ideally suited to medium-sized listening rooms, this 3-way loudspeaker delivers an expansive soundstage, articulate midrange, and dynamic bass performance without demanding a large footprint.

Despite its slender proportions, Lumina III houses four drivers, including a dedicated midrange and two woofers, in a carefully engineered vented enclosure. Its down-firing reflex port provides greater flexibility in speaker placement, while its beautifully finished wood front baffle and hand-applied leather surfaces make it as appealing to look at as it is to listen to.

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.

A Four-Driver, 3-Way Design

Lumina III uses a 3-way configuration that allows each driver to operate within a carefully defined frequency range. High frequencies are handled by Sonus faber's 29 mm DAD (Damped Apex Dome) tweeter, featuring a hand-coated silk diaphragm and viscoelastic decoupling from the front baffle. This technology, also used in the Sonetto collection, helps control dome resonance and delivers smooth, extended treble reproduction.

A dedicated 150 mm midrange driver, derived from designs in the Sonetto collection, employs a diaphragm made from a blend of cellulose pulp and natural fibers. Engineered for high linearity and dynamic responsiveness, it reproduces voices and acoustic instruments with the tonal accuracy and expressive character central to the Sonus faber sound.

Two additional 150 mm woofers, developed specifically for the Lumina series, use paper-pulp cones chosen for their sonic coherence with the midrange driver. Together, they provide the bass extension and dynamic authority expected from a floorstanding loudspeaker while maintaining a consistent tonal balance across the frequency spectrum.

Optimized Crossover and Flexible Placement

Sonus faber's Para-cross crossover topology is designed to optimize the amplitude and phase relationships between the drivers, supporting precise imaging and a coherent soundstage. Crossover frequencies of 350 Hz and 3,500 Hz ensure a controlled transition between the woofers, midrange, and tweeter.

The bass-reflex port is positioned at the bottom of the enclosure, firing downward through the speaker's base. This arrangement makes Lumina III less sensitive to rear-wall proximity than conventional rear-ported designs, offering greater flexibility when positioning the speakers in a living room or dedicated listening space.

Dual sets of binding posts allow bi-wiring or bi-amping, giving owners additional flexibility when configuring or upgrading their systems.

Italian Craftsmanship and Contemporary Style

Lumina III combines a minimalist cabinet profile with the materials that have long distinguished Sonus faber loudspeakers. The 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 covered by hand in black leather, creating an understated contrast with the front baffle.

Chrome-finished trim rings around the drivers add a subtle visual accent, while the compact cabinet proportions help Lumina III integrate comfortably into a wide range of interiors. The result is a loudspeaker that expresses Sonus faber's design heritage without overwhelming the room.
