Avantgarde Acoustic Opus 1
The Opus 1 refreshes horn listening with revealing inner detail, expansive frequency extension and the unmistakable immediacy of a horn-loaded design. Part Time Audiophile finds this active two-way reaches further at both extremes than classic horn rivals, making it a compellingly modern route to vivid, full-range-scale sound.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 81/100
The available review finds the Opus 1 recognisably horn-like, while crediting it with greater inner detail and stronger extension at both frequency extremes than traditional horn designs. It offers encouraging evidence of clarity and range, but says little about imaging, dynamic behaviour, tonal balance through the midrange, or setup sensitivity.
Bass
84/100
Part Time Audiophile reports more extension at the frequency extremes than is typical of classic horn-loaded designs, which supports a positive view of the low end. The review does not describe bass depth, texture, room interaction, or control in detail.
Mid
82/100
The reviewer hears greater inner detail from the Opus 1, suggesting a more revealing presentation than conventional horn speakers. There is little direct discussion of vocal timbre, tonal warmth, or coherence around the crossover region.
Treble
85/100
The review specifically praises improved high-frequency extension and greater inner detail. It does not address whether the treble remains consistently smooth or forgiving with brighter recordings.
Soundstage Imaging
75/100
The available review does not discuss stage width, depth, image focus, or placement behaviour. Buyers looking for evidence about spatial performance will need more listening reports.
Dynamics
75/100
The review identifies the speaker's classic horn character but provides no direct account of transient impact, large-scale swing, or composure at high volume. Its dynamic character is therefore not well documented in the supplied coverage.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
75/100
The supplied review offers no direct assessment of cabinet finish, fit and finish, hardware, or long-term durability. Product information lists MDF and aluminium construction, adjustable spikes, and a substantial 39 kg enclosure, but reviewer commentary on execution is absent.
Value for Money
85/100
At $18,500, the Opus 1 sits in a specialist high-end active loudspeaker segment. None of the supplied reviews directly assess whether its performance, amplification, and horn design justify that asking price against competing speakers.
