AVANTGARDE Opus 1

Precision from Odenwald.
Engineered to Last.

When you choose Avantgarde, you expect a horn system built to stand the test of time. Horn systems are, by nature, the most efficient and sustainable way to transform the energy of music into sound. We follow the same principle in our engineering: the components that matter are crafted to last for decades, while fast-moving technologies like streamers remain external – easy to upgrade, and independent of the loudspeaker. Hand-built in the Odenwald, where things are still made with patience, intention, and a belief in durability, OPUS 1 becomes a long-term companion – engineered to perform far beyond ordinary product cycles.

A new dimension of a full-range system by Avantgarde

OPUS 1 is the first Avantgarde system built around a single wide-band horn: a 13.8-inch spherical wave geometry capable of reproducing the entire critical midrange and high-frequency spectrum from 700 to 20,000 Hz, accompanied by a 10" bass driver. By concentrating the musical core into one horn, we eliminate crossover transitions in the most sensitive bandwidth, resulting in seamless coherence, sharp transient response, and a presentation that feels alive, direct, effortless.

Huge Bass.
Minimal Footprint.

You want bass that’s clean, deep, and physical – the kind that turns sound into presence. That’s exactly what the OBM10 driver was created for. Its 10″ inverse natural-fiber-cone construction delivers speed and impact, the dedicated 250-watt amplifier provides authority, and the optimized port design keeps everything tight, tuneful, and room-friendly. This is low end – the Avantgarde way.

A High-End Active System.
Perfectly Integrated.

High-end performance is never accidental – it happens when every part of a system works as one. That’s the principle behind the integrated amplification inside OPUS 1. Engineered in-house by the minds behind our celebrated amplifier innovations, every stage is precisely tuned to the acoustic behavior of the speaker. The result is a perfectly matched architecture that removes system-matching uncertainty, preserves a pure signal path, and unleashes the full musical presence the horn was built to deliver. With intuitive manual bass management for adjusting to room size and placement, and amplification shaped exclusively for this system, OPUS 1 performs with the ease and coherence of a single musical instrument. No amp choices. No setup hurdles. Just effortless high-end from day one.
