d&b audiotechnik - SL-GSub

The d&b audiotechnik SL-SUB is a high-performance, professional subwoofer designed for large-scale events demanding deep, highly directional low-frequency reproduction. The cabinet houses three 21-inch woofers — two facing forward and one rearward — delivering effective cardioid dispersion. This keeps maximum energy directed at the audience while keeping the stage quiet and free from unwanted low-end buildup. Delivering a maximum sound pressure level of 144 dB SPL and a frequency response from 33 Hz to 84 Hz (extending down to 30 Hz in INFRA mode), this 138 kg unit produces exceptional output. Driven by powerful d&b D80 or D90 amplifiers, the SL-SUB features integrated rigging hardware to safely fly columns of up to 14 cabinets, whereas the companion SL-GSUB is specifically designed for ground-stacked applications.
