Welcome to the new Opus Audio Developments website, which will be continually developed and expanded over the coming months. We may lag behind some of our competitors in marketing because we focus on our products, where we lead in sound quality - so we make no apology for our priorities. If you haven’t heard Opus yet, please contact us and we’ll be pleased to arrange a demo against any other system - we are confident you’ll hear, and appreciate, the difference.
At Opus we recognise no limits in the pursuit of pure sound and so, aiming for perfection, we set out to imagine a new kind of sound system.
A system which really is a system, in which each component is matched and designed to work as part of the whole. In which clipping and distortion are a thing of the past. In which drivers are supremely loud and yet are never over-driven. In which sound field dispersion and coherence are precisely controlled.
We dreamt of a system powered by the world’s most detailed ultra-fi amplifiers with cooling systems so efficient that they never even run hot, let alone overheat.
A system in which breathtaking sound quality go hand in hand with proven reliability. A system guaranteed to stay working year after year in the most hostile environments.
We imagined it and it is no longer a dream. It is real and it is available now. We call it the Opus Integrated System.
We sell only complete systems because only by controlling the quality and matching of every component can overall fidelity and reliability be guaranteed. And we do, every Opus Integrated System is commissioned with a full 3 year warranty ...
Professional reinforcement loudspeaker systems featuring exceptional efficiency and clarity
for the professional concert touring, rental and installation contractor markets.
During the early eighties a small group of Belgian Audio Professionals aligned themselves with respected mathematician and locally renowned Audio system designer Mr. Marcel Put, to develop a loudspeaker that would sound totally natural whenever loud music was desired or needed. From a modest laboratory and test facility, located in his native town of Lummen in Belgian Limburg, Mr. Put embarked on an extensive research project with the objective of finding a solution to the excessive levels of distortion typically experienced from listening to medium and medium/high frequency spectrums produced by loudspeaker system used for live sound touring purposes at the time.
As a result of burning lots of proverbial “midnight oil” Mr.Put recognized that it was not possible to offer a solution to this problem within the confinements of the commonly practiced way of utilizing horn loaded compression drivers to reproduce medium and high frequencies. The core of the problem was found in that at high SPL levels these horn loaded electro-magnetic transducers deliver as much as 25 to 50% unwanted but very audible and annoying harmonic distortion. Another approach was called for ...
