The Y-SUB is a high-performance, flyable cardioid subwoofer from d&b audiotechnik's Y-Series, designed for precise low-frequency reproduction in both mobile and installation settings. It features two long-excursion neodymium drivers: a front-facing 18" bass-reflex driver and a rear-facing 12" bandpass driver, creating a cardioid dispersion pattern that minimizes energy behind the system. This configuration enhances clarity and reduces unwanted reflections. The Y-SUB is constructed from marine plywood with a durable, weather-resistant finish, ensuring reliability in various environments. It offers multiple rigging options, including flying in a column, mounting at the top of a Y array, or ground stacking, providing versatility for different deployment scenarios.
