1.125" D.A.D. (Damped Apex Dome) Tweeter: The Lumina III floorstanding loudspeaker features Sonus faber's iconic D.A.D. (Damped Apex Dome) tweeter with a 1.125" hand-coated soft silk diaphragm and Sonus faber's exclusive visco-elastically baffle decoupling for exceptional high frequency reproduction.

Triple 6" Cellulose Pulp Cone Drivers: The Sonus faber Lumina III floorstanding speaker houses one 6" midrange driver and two 4.75" bass drivers with custom-made cellulose pulp cones blended with other natural fibers, robust rubber surrounds, and specially-designed, ultra-free compression baskets for a natural sound that is both dynamic and linear with high clarity midrange frequencies and deep, accurate bass notes.

Para-Cross Topology Crossover: The Lumina III floorstanding speaker employs a 3-way crossover with Para-cross topology. Para-cross topology is a "semi-balanced" crossover design circuitry, where some components (capacitors and inductors/coils) are placed on the negative rail of the circuit to lessen the sensitivity of radio-frequencies and provide a better definition of sound.

Bass Reflex Multi-Layer Wood Enclosure: The Lumina III floorstanding speaker uses a multi-layer wood cabinet with a real-wood veneer front baffle that is available in a Walnut, Wenge, or Black finish. The outer sides and top of the speaker enclosure are covered with a black leather material. The included cloth grille magnetically attaches to the front of the speaker. The cabinet is a bass reflex design with a down-firing port for greater extension in low frequencies and reduction of distortion. The down-firing port also allows for more placement options, allowing you to even place the speaker closer to a back wall.

Dual Nickel-Plated Binding Post Terminals: The Lumina III has two sets of nickel-plated binding posts connected by jumpers. Using the dual binding posts, you can bi-amp or bi-wire the speakers (make sure to remove the jumpers in this scenario). The binding post terminals will accept banana plugs (single only), pin-connectors, spade-connectors, and bare wire (up to 10AWG). The nickel-plated binding post terminals provide excellence signal transfer and resistance to corrosion.

• Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
• Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.

Mounting & Placement Options: The Lumina III floorstanding loudspeaker is perfect for stereo listening, but is also ideal for use as front or rear channels in a home theater setup. The Sonus faber Lumina III features an integrated plinth (base) and includes spike feet for carpeted floors; as well a protective discs to fit under the spike feet to protect your hardwood, tile, laminate, or vinyl flooring. With the protective discs underneath the attached spike feet the speaker measures 38.9375" tall. With only the spike feet attached the speaker measures 38.875" tall.

• You should position a pair of speakers so they form an equilateral triangle with one another and the main seated listening position.
• The two floorstanding loudspeakers should be at least 6' apart from each other.
• The pair of speakers can be "toed-in" and angled inward to aim the sound at the main listening area for a better stereo soundstage.
• It is recommended to position the speakers away from the corners of the room, and at a distance of at least 3.3125' from the back wall.

Lumina Collection: The Lumina collection pays tribute to Sonus faber's historic heritage and are made in Italy. The Lumina series boasts the core values of Sonus faber with the use of its iconic materials - including leather, natural composition of drivers, and real multilayer wood cabinets. The Lumina line-up consists of two floorstanding loudspeakers (Lumina III/Lumina V), two bookshelf loudspeakers (Lumina I/Lumina II), and a center-channel speaker (Lumina CI). The Lumina collection delivers uncompromised sound performance that is perfect for a two-channel stereo setup or a multi-channel home theater system.

Optional Subwoofer: Add on a Sonus faber Gravis series powered subwoofer (Gravis I/Gravis II) for an even more immersive listening experience with bigger, deeper, and more impactful bass.
