The d&b audiotechnik J-INFRA is a high-output cardioid subwoofer engineered to extend system bandwidth with exceptionally clean, ultra‑low frequency energy. Housing three 21-inch drivers in a purpose-built enclosure, it delivers impactful infrabass while maintaining outstanding pattern control, keeping low-frequency spill off the stage and away from reflective surfaces. Designed to integrate seamlessly with the d&b J-Series and other large-format arrays, the J-INFRA provides formidable headroom and consistent performance in demanding touring and installation environments. Front and rear amplification channels are employed to achieve the cardioid response, ensuring precise, musical low end that remains tight and controlled even at arena and festival scale. Rugged construction and Neutrik NLT4 male/female connectors support reliable deployment, while the supplied transport lid and protective cover help safeguard the cabinet between shows. Ideal for large-scale touring, stadium concerts, high-SPL dance events and premium installations where deep, controlled infrabass is essential.
