Overview
Five drivers housed in a dual cabinet with sculpted curves, 90 kilos per speaker, and a frequency response from 30 Hz to 30 kHz: the XS-85 embodies Gold Note’s vision of what an unrestricted floorstanding speaker should be. Conceived in the workshops of Montespertoli, near Florence, this large Italian floorstander brings together the Tuscan manufacturer’s expertise in a monumental format where every technical choice serves a natural, dynamic sound reproduction.
A dual cabinet inspired by the Renaissance
The silhouette of the XS-85 immediately stands out thanks to its curved lines, derived from a geometric principle Gold Note calls the “catenary curve,” in reference to Michelangelo’s work on self-supporting architectural structures. This absence of parallel faces is not merely aesthetic: it eliminates standing wave resonances that typically affect rectangular speakers and significantly increases cabinet rigidity.
The construction uses a multilayer sandwich structure. The front baffle and side panels reach 45 mm in thickness thanks to a double layer of curved panels. The rear panel incorporates a 10 mm ventilated metal brace, while the top features a massive 100 mm panel designed to simulate an open baffle and evacuate internal reflections. A 3 mm laser-cut aluminum plate provides structural coupling between the two cabinets and contributes to overall rigidity. The base rests on a 3 mm stainless steel platform equipped with concealed adjustable spikes and a slight 2° backward tilt to optimize time alignment.
The internal architecture physically separates the frequency ranges. The lower cabinet houses the two woofers in a vented volume with two aluminum anti-turbulence bass-reflex ports. The upper cabinet accommodates the two midrange drivers in sealed chambers, as well as a second open cavity with a solid aluminum grille to reduce unwanted reflections and improve rigidity.
Drivers developed with SEAS and Ehmann
Gold Note partnered with Norwegian specialist SEAS for the design of the four cone drivers. The two 22.86 cm woofers and two 15.24 cm midrange drivers share a common architecture: Nextel-coated paper cones, particularly low moving mass (around 6 grams for the woofers), aluminum phase plugs to prevent cone deformation under high excursion, and rubber surrounds with adaptive compliance. The Nextel coating gives the cones a balance between rigidity and damping that promotes a fast, natural response.
The 28 mm silk dome tweeter was custom-developed by Ehmann, a German manufacturer renowned for its high-end transducers. Its design is distinguished by the absence of ferrofluid in the gap, which preserves treble transparency, with thermal management entrusted instead to an elliptical aluminum rear chamber. The neodymium magnet and copper hex-wire voice coil ensure a linear response up to 30 kHz.
Triple-network crossover with resistive loading
The XS-85’s passive crossover uses a three-network Dual-Slope topology, with crossover points at 200 Hz and 2200 Hz and 12 dB per octave slopes. The midrange section features a “multi-slope summing” design that optimizes integration between the two 15 cm drivers and ensures a smooth handover to the tweeter.
The thick, anti-resonant fiberglass PCB carries carefully selected components: audiophile-grade polypropylene capacitors, hand-wound air-core inductors, and exclusive graphite resistors developed by Gold Note. The semi-resistive design allows the impedance to remain stable despite a nominal value of 4 Ω, which eases the workload of the power stage and allows the use of amplifiers with modest wattage, provided they can deliver sufficient current.
Integration and placement
With a sensitivity of 89 dB and semi-resistive impedance, the XS-85 is easy to drive from around 30 watts, while handling up to 300 W RMS for the most dynamic passages. The recommended minimum listening distance is between 1.5 and 2 meters, making this speaker more suitable for medium to large-sized rooms.
Connection is via rhodium-plated Gold Note binding posts, and the internal wiring uses the brand’s own conductors. The damping material inside the cabinets favors natural fibers over synthetic foams, a choice that influences bass texture and the overall “breathing” of the speaker.
Italian handcrafted finishes
Each pair of XS-85 is hand-assembled in Gold Note’s Tuscan workshops. The main cabinet comes in a black finish, while the side panels offer three options: genuine gold leaf for strong visual impact, ultra-gloss Italian walnut for a classic, warm touch, or high-gloss piano black for a more discreet integration. The 90 kg weight per speaker, combined with generous dimensions (36 cm wide, 1.28 m high, 66.5 cm deep), calls for careful and ideally final placement.

Frequently Asked Questions
What kind of amplifier is suitable for the XS-85?
Thanks to its semi-resistive impedance, the XS-85 is quite forgiving in terms of amplification. A unit delivering 30 W into 4 Ω is sufficient for everyday use, but electronics capable of supplying high current into low impedances will better exploit the woofers’ dynamic potential. Tube amplifiers also work, provided they have a suitable 4 Ω output.
How do you move and install these 90 kg speakers?
The cabinet splits into two modules (bass section and mid/high section), which makes handling easier on stairs or through narrow passages. Gold Note supplies the assembly dowels required to join the two elements. Plan for at least two people for final setup.
Can the bass-reflex ports cause issues when placed near a wall?
The rear anti-turbulence ports have been optimized to limit airflow noise, but placing the speakers too close to the back wall (less than 30 cm) may thicken the bass. A distance of 50 to 80 cm between the rear of the speaker and the wall generally provides a good balance.
Are protective grilles included?
The XS-85 does not come with removable grilles. The drivers remain exposed, which is an integral part of the design. The Nextel cones are relatively resistant to accidental handling, but environments with young children or pets require particular care.
How much break-in is needed to reach optimal performance?
Gold Note recommends a break-in period of about 100 to 150 hours of listening. The Nextel paper cones and rubber surrounds gradually become more compliant, which mainly refines bass reproduction and coherence across the frequency ranges.
Is it possible to bi-amp or bi-wire the XS-85?
The single binding post does not offer a native bi-wiring configuration. The internal crossover manages distribution between drivers in an optimized way for single wiring. A modification of the internal wiring would be required to consider bi-amping, which is not recommended by the manufacturer.
