Floorstanding loudspeakers — Avantgarde Acoustic Opus 1

The Opus 1 is a convenient horn-loaded floorstanding loudspeaker from Avantgarde Acoustic, built with staggering sensitivity and substantial built-in amplification. The Opus 1 brings Avantgarde's legendary horn-loaded engineering heritage to a convenient active floorstanding format.

Key specs that matter

Rated response is 35Hz to 22,000Hz within plus-or-minus 3dB. Sensitivity is a staggering 103dB into the standard 8 ohm load - an extraordinary figure among the highest efficiency figures available in any commercial loudspeaker. Internal amplification delivers a substantial 360W. At 110 x 35 x 36cm and 39kg, the Opus 1 maintains a manageable horn-loaded floorstanding chassis given its substantial built-in amplification.

Sound and use context

Expect the immediate, dynamically alive character Avantgarde's legendary horn-loaded driver technology is broadly celebrated for, with the staggering 103dB sensitivity combined with the substantial 360W built-in amplification providing convenient, capable dynamic performance.

Pairing

As a fully active design, the Opus 1 requires no external power amplifier, connecting directly to a source component or preamplifier with line-level input.

Alternatives

Avantgarde's own DUO series offers passive horn-loaded alternatives requiring external amplification within the same broader catalogue.
