More in-depth information and insights about the concept, design, and creation of the unique Kaliber Technology Ulysse X5 speakers, made from ultra-rigid magnesium alloy.
The Kaliber Ulysse X5 is not just an ordinary loudspeaker — it is a paradigm shift
in acoustic innovation and mechanical design. As the world’s first loudspeaker
built from solid magnesium blocks, Ulysse X5 sets new benchmarks in
vibrational damping, structural rigidity, and sonic purity.
Every detail of its architecture—from driver selection to cabinet material—has been meticulously engineered for absolute fidelity.
At its core, Ulysse XVD combines state-of-the-art drivers from SEAS, ScanSpeak, and
AudioTechnology with an advanced hybrid crossover architecture, a patented
aluminum low frequency cabinet base design, and a unique mechanically decoupled
driver layout featuring Solid Block CNC Magnesium Mid-Hi Cabinet. It delivers a
seamless, holographic soundstage with a visceral low-end foundation and refined
microdetail, elevating the listening experience into a realm of pure emotion and
realism.
Performance Highlights
- Unparalleled Cabinet Inertia: Eliminates micro-vibrations and resonance
buildup. - Hybrid Precision: Seamless passive-to-active crossover integration for
uncompromising performance. - Custom-Tuned Bass: DSP-corrected subwoofer ensures room-matched low-
frequency extension. - Ultrafine Imaging: Mechanically decoupled, angle-adjustable Mid-Hi
ensures ideal axis response. - Monumental Presence: Massive 500+ kg system weight per channel
ensures absolute stability and sonic authority.
Key Features
Magnesium Block Construction – First in the World
- Mid-Hi Loudspeaker cabinets CNC milled from solid magnesium blocks for
ultra-low resonance and maximum rigidity. - Provides near-zero vibration, eliminating enclosure coloration and
maximizing transient precision. - Mid-Hi module and Woofer/Subwoofer module are acoustically and
mechanically isolated. - Woofer and Subwoofer cabinets CNC milled from solid magnesium plate
almost 80 mm. thickness with aluminum internal matrix brace.
Tweeter & Midrange: Magnesium Satellite Module
- 1″ SEAS Custom Diamond Dome Tweeter
o Diamond diaphragm for extreme stiffness and breakup-free response
beyond 50 kHz.
o Delivers crystal-clear highs with breathtaking resolution and speed.
o Housed in an independent closed unit block of magnesium
enclosure for minimal interference. - 4″ ScanSpeak Illuminator Midrange
o Open chassis and AirCirc motor system provide unmatched midrange
clarity and low distortion.
o Housed in an independent magnesium enclosure with special
non resonance back chamber for ultra clean, and minimal
interference. - Satellite module includes tilt-adjustable mounting, controlled via rear
precision knob for fine vertical angle tuning, optimizing time alignment
and directivity in room.
Woofer & Subwoofer Module: Dual-Chamber Magnesium Enclosure
- 2 × 7″ ScanSpeak Illuminator Woofers
o High-precision dual woofers handle bass and lower midrange with
lightning-fast transient response. - 15″ Custom AudioTechnology Subwoofer
o 4” Voice Coil with large size magnet to meet Ulysse X5 custom spec
o Housed in a custom ported magnesium sub-bass chamber.
o Features its own dedicated active DSP crossover and external
high-current amplifier, enabling real-time room correction and
precise low-frequency tuning for seamless integration.
Crossover Architecture
- Passive crossover for 1″, 4″, and dual 7″ drivers using top-grade
components. - Active DSP crossover for 15″ subwoofer with full parametric control
and time alignment. - Duelund CAST Components in midrange and tweeter path for unmatched
tonal purity, transparency, and harmonic richness. - External Crossover Enclosure
o Isolated in a separate 120 kg acrylic chassis for mechanical decoupling.
o Built for ultimate clarity and noise immunity.
o Special design anti vibration footer
Base & Foundation
- Loudspeaker rests on a T6061 Solid Aluminum Base Plate featuring
Kaliber’s patented Varicurv™ geometry, engineered to control resonant
flow and vibration propagation. - Ensures ultra-stable grounding, deep bass anchoring, and stunning spatial
stability.
