The cabinet of Opera Prima was developed with a rigorous approach from the very first design stages. Its proportions were carefully redefined to break up standing waves and minimize localized resonances. A high-density polyurethane material was used as internal damping, reducing residual reflections by more than an order of magnitude.

Measurements confirmed an extremely fast decay of the unavoidable resonances in the lower-midrange area. In listening terms, this translates into a remarkably clean and accurate reproduction, capable of rendering even the most subtle spatial cues and harmonic details with fidelity.

Internal bracing was reduced to the bare minimum to avoid adding unnecessary mass or rigidity that could introduce new colorations. The top and bottom panels are angled with specific inclinations designed to reduce mutual interaction and optimize the distribution of internal waves.

In keeping with Opera’s tradition, the driver recess is internally chamfered to minimize compression effects, particularly in the midrange. The rear-firing reflex port has been carefully tuned to deliver controlled low-end extension without compromising transient speed or harmonic coherence.
