The Avantgarde UNO SD: The Engineering Behind Its Stunning Sound
A quick look at the engineering choices behind the UNO SD, and how each one contributes to its acoustic performance.
The UNO SD combines a two-way spherical horn system with an active subwoofer, achieving exceptional efficiency, linearity, and control.
A 500 mm midrange horn (290 Hz–4 kHz) and 100 mm tweeter horn ensure constant directivity and minimal distortion. The tweeter horn’s THD measures below –50 dB of the actual music signal, ensuring exceptional high-frequency purity and transient accuracy.
All drivers use Avantgarde’s proprietary Omega voice coils with an 18-ohm impedance, allowing effortless pairing with both tube and solid-state amplifiers while maintaining stable electrical behavior. The coplanar alignment of the drivers ensures phase accuracy and time coherence across the frequency range, resulting in precise imaging and natural spatial presentation.
The active bass module employs dual 10-inch long-throw drivers powered by a 500 W DSP-controlled amplifier, extending cleanly to ~18 Hz. The DSP provides perfect crossover integration using a spheric low-cut filter, maintaining seamless phase and tonal balance between the horns and bass system.
Rigid composite horn structures, precisely damped enclosures, and meticulous German craftsmanship guarantee mechanical stability, low resonance, and long-term reliability.
Beyond the engineering, the UNO SD complements a luxury audiophile lifestyle: a system designed not only for sonic truth but also for the aesthetic and emotional pleasure of owning a genuine high-end work of art.
