The d&b audiotechnik J-INFRA is a high‑output cardioid subwoofer designed to extend system bandwidth with exceptionally clean, ultra‑low frequency energy. Housing three 21‑inch drivers in a purpose‑built enclosure, it delivers authoritative infrabass while maintaining outstanding pattern control to keep low‑frequency spill off the stage and away from reflective surfaces. Engineered to integrate seamlessly with the d&b J‑Series and other large‑format arrays, the J‑INFRA provides formidable headroom and remarkable consistency for demanding touring and installation applications. Cardioid performance is achieved via dedicated front and rear amplification channels, ensuring precise, musical low end that remains tight and controlled, even at arena and festival scale. A rugged cabinet with Neutrik NLT4 connectors supports reliable deployment, while the supplied transport lid and protective cover help safeguard the enclosure between shows. Ideal for large‑scale touring, stadium concerts, high‑SPL dance events and premium installations where deep, controlled infrabass is essential.
