Basshorn systems are a myth and enjoy a legendary but at the same time – when they are constructed too small – an ambivalent reputation. Too small dimension will inevitably cause bouncy impedance curves and a boomy frequency response. That´s the law of physics. That´s the challenge. And that´s where Avantgarde Acoustic™’s technological leadership comes into play. Introducing ADRIC, the worlds only technology to surpass the physical constrains in bass horn design.

The proprietary “Active Dynamic Radiation Impedance Compensation” technology of Avantgarde Acoustic™ ensures that relative small hornsize and overwhelming low frequency extension does not necessarily exclude. ADRIC is based on our fundamental research of the electro-acoustical interdependencies of wavefronts being induced in horn funnels. The complex ADRIC circuits detect the characteristic impedance peaks and precisely compensate through ultrafast analogue feedback loops.

The compensation is precisely calibrated and linearized. It is determinative and predictable. It is nimble and subtle. It is sensitive and agile, ensuring that the bass response is crisp, instantaneous and without the slightest soupçon of protraction. Perfect, legendary, unforgettable.

Tall, purposeful and elegant, the Duo Primo communicates performance and agility. Perfect proportions with a sophisticated and desirable proposition. Each system is made to order: by skillful hands, with ultimate care and precision, employing esteem and respect to their becoming owner, taking an endless 70 days to complete.

It simply is the most personal and intense form of the unforgettable Duo experience.
