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-inch inverted paper cone 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 DSP-based bass tuning that adapts naturally to real rooms, 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.
