The d&b audiotechnik J-INFRA is a dedicated infra-bass subwoofer engineered to push J-Series systems confidently into the lowest octave. Tailored for touring and large-scale installations, it delivers exceptionally coherent, musical low frequencies with the headroom and control expected from d&b. Designed to couple seamlessly with J‑SUB and J‑Series tops, it maintains consistent directivity and voicing across complex arrays for tight, impactful low-end that remains articulate at scale.
Built for the road, the J‑INFRA features robust construction, precise rigging compatibility and connection variants including EP5, NL4 or NLT4 for straightforward integration with established cabling standards. A supplied front lid safeguards the grille and drivers during transport and storage, supporting quick turnarounds and dependable deployment in demanding environments.
Whether deployed in ground-stacked arrays or integrated into flown configurations, the J‑INFRA excels in festivals, arenas, stadiums and high-SPL productions where controlled infra extension is essential. Choose it when you need deep, authoritative bass that complements J‑Series systems without compromising clarity or coverage.
