The Sweet Spot Between Compact Design and Full-Range Sound.

Italian-Made 3-Way Floorstanding Loudspeaker

The Sonus faber Lumina III brings the presence of a floorstanding loudspeaker into a beautifully proportioned cabinet that feels right at home in a modern living space.

Standing just under 39 inches tall and only 9 inches wide, the Lumina III combines a dedicated midrange driver, dual woofers, and Sonus faber's signature Damped Apex Dome (D.A.D.) tweeter in a sophisticated three-way design.

The result is a speaker engineered to deliver the scale and dynamic impact of a tower while preserving the natural vocals, instrumental detail, and elegant craftsmanship that define the Sonus faber experience.

A down-firing bass-reflex port provides useful placement flexibility, while the cabinet's multilayer wood front baffle and hand-applied black leather bring a distinctive touch of Italian luxury.

Designed and manufactured in Italy, the Lumina III is an inviting choice for music lovers who want a serious stereo system without overwhelming their room.

Beautifully proportioned. Musically ambitious. Unmistakably Sonus faber.

 

A Floorstanding Speaker That Fits Your Life

Not every listening room calls for a massive loudspeaker.

The Lumina III was developed with medium-sized spaces in mind, offering a slender footprint without sacrificing the advantages of a dedicated three-way system.

Its cabinet measures approximately 38.9 inches tall, 9 inches wide, and 10.9 inches deep. That makes it easy to integrate into living rooms, apartments, and dedicated listening spaces where floor space and visual balance matter.

Unlike a bookshelf speaker, the Lumina III doesn't require separate stands. Its dedicated bass drivers also give it a broader low-frequency foundation than the smaller Lumina models.

With specified bass extension down to 40 Hz, it is capable of reproducing a substantial portion of the musical spectrum on its own. A subwoofer remains an option for listeners who want deeper bass or a complete home theater system.

Four Drivers. Three Ways. One Cohesive Sound.

The Lumina III uses a dedicated driver for each major part of the musical spectrum, allowing its tweeter, midrange, and woofers to concentrate on the frequencies they are designed to reproduce.

29 mm Damped Apex Dome tweeter

The high-definition D.A.D. tweeter incorporates a hand-coated soft-silk diaphragm and an apex-damping system designed to control unwanted dome movement.

Viscoelastic decoupling helps isolate the tweeter from vibrations transmitted through the front baffle.

It handles the upper frequencies, reproducing the subtle details of cymbals, strings, vocal harmonics, and recorded ambience.

Dedicated 150 mm midrange

The Lumina III's midrange driver draws on technology developed for the Sonetto collection.

Its diaphragm combines paper and natural fibers, reflecting Sonus faber's approach to reproducing voices and instruments with convincing tonal character.

By assigning the midrange its own driver, the Lumina III separates this critical musical information from the demands of deep bass reproduction.

Dual 150 mm woofers

Two 6-inch woofers provide the low-frequency foundation.

Developed specifically for the Lumina collection, their paper-pulp cones are designed to complement the midrange driver's material characteristics.

Together, they provide the body and impact needed for bass guitar, drums, piano, and larger orchestral recordings.

 

A Crossover Designed to Bring Everything Together

Four drivers only become a great loudspeaker when they work as one.

The Lumina III incorporates Sonus faber's Paracross crossover topology, with crossover frequencies of 350 Hz and 3,500 Hz.

The network divides the audio signal between the woofers, midrange, and tweeter while optimizing their amplitude and phase relationships.

This allows the dedicated midrange to handle the heart of the music, the woofers to provide low-frequency authority, and the tweeter to reproduce the finest details.

The goal is a coherent presentation in which you hear the performance rather than individual drivers competing for attention.

Bass That Works With Your Room

The Lumina III features a down-firing bass-reflex port positioned at the base of the cabinet.

Instead of directing the port straight toward the rear wall, this arrangement vents downward through the speaker's base.

It provides additional flexibility when positioning the speakers in real living spaces, including installations where the cabinets need to sit relatively close to a wall.

Speaker placement still matters. Distance from boundaries, listening position, and room acoustics all influence the final bass response, but the down-firing design gives installers and homeowners a useful starting point.

Iron spikes are included to help establish stable floor coupling.

 

Italian Craftsmanship, Three Distinct Finishes

Sonus faber has always understood that a loudspeaker is part of the room, not simply a piece of equipment placed inside it.

The Lumina III combines a multilayer wood front baffle with black leather hand-applied to the cabinet's sides and top. Chrome rings surrounding the drivers add a refined finishing touch.

Choose from three distinctive appearances:

• Piano Black: High-gloss lacquer for a clean, contemporary aesthetic.

• Wenge: Dark wood veneer with contrasting maple inlays.

• Walnut: Warm wood veneer with maple inlays for a more traditional character.

Every finish reflects the natural materials and understated styling associated with Sonus faber's Italian heritage.

Made for Music. Ready for Movies.

The Lumina III is equally comfortable at the heart of a dedicated stereo system or as the front left and right speakers in a home theater.

For two-channel listening: Pair the Lumina III with a capable integrated amplifier and a quality streaming source, turntable, or digital front end. Its three-way architecture and dual woofers make it a compelling foundation for a full-size music system.

For everyday living: Its narrow cabinet and down-firing port help it integrate into spaces where performance, appearance, and placement flexibility are equally important.

For home theater: Use the Lumina III as the main left and right channels alongside a compatible Sonus faber center speaker, surrounds, and subwoofer for a cohesive multichannel system.

The speaker has 89 dB sensitivity, a nominal 4-ohm impedance, and a recommended amplifier power range of 50–250 watts. Choose an amplifier capable of driving a 4-ohm load comfortably, particularly if you listen at higher volumes or in a larger room.
