The d&b audiotechnik J-INFRA is a dedicated infra-bass subwoofer designed to extend the low-frequency performance of J‑Series systems into the deepest octave. Built for touring and large-scale installations, it delivers coherent, ultra-low frequency reinforcement with the clarity, headroom and control expected from d&b systems. Connection variants include EP5, NL4 or NLT4, ensuring straightforward integration with a range of cabling standards and existing d&b infrastructures. A supplied front lid protects the cabinet during transport and storage, supporting efficient turnarounds on the road.
Engineered for seamless coupling with J‑SUB and J‑Series tops, the J‑INFRA maintains consistent directivity and sonic character across complex arrays. Its robust construction, precise rigging compatibility and system-led approach make it a reliable choice for festivals, arenas, stadiums and high-SPL touring productions where impactful, controlled infra-bass is essential.
Whether deployed in ground stacks or integrated within flown configurations, the J‑INFRA is ideal for delivering powerful, musical low-end extension for live music, dance events and large-format sound reinforcement.
