The d&b audiotechnik J-INFRA is a high-performance infra subwoofer designed to extend system bandwidth with deep, coherent low frequency energy. Built to partner seamlessly with the J-Series, it delivers exceptional low-end extension and pattern control, helping large-format PA systems maintain punch, clarity and headroom at the very bottom of the spectrum. Its optimised enclosure and integrated cardioid performance minimise rear radiation, improving onstage conditions and reducing unwanted low-frequency build-up in reflective spaces. Engineered for the demands of touring, the J-INFRA features robust construction, industry-standard connectors and straightforward rigging and deployment within d&b system workflows. When driven by appropriate d&b system amplifiers and presets, it integrates quickly into arrays or ground stacks, supporting precise time alignment and consistent results show after show. A proven choice for concerts, festivals and large venues where authoritative, controlled sub-bass is essential. Perfect for touring sound companies, arena installations and high-impact live events.
