The 24S loudspeaker is a high-specification, full-range passive speaker system developed by d&b audiotechnik for fixed installation in professional environments. Designed to deliver consistent audio performance across a wide range of venues, the 24S loudspeaker incorporates a two-way configuration with dual 12-inch drivers and a 1.4-inch compression driver, mounted on a rotatable constant directivity horn. This layout supports precise dispersion control and ensures intelligible audio reproduction, even in acoustically challenging spaces. Engineered for venues such as theatres, concert halls, houses of worship, sports arenas, and multipurpose auditoriums, the 24S loudspeaker is well suited to both voice and music reinforcement. Its robust bass-reflex enclosure, combined with optimised porting and substantial cabinet volume, enables extended low-frequency response, reducing the need for additional subwoofers in some applications. The 24S loudspeaker operates within a frequency range of 55 Hz to 18 kHz and is capable of being deployed as a standalone solution or integrated into larger distributed sound systems. Constructed from marine-grade plywood and finished with a hard-wearing paint coating, the enclosure is built to meet the demands of high-use professional installations. Available in a Weather Resistant version with an IP55 rating, the 24S loudspeaker can also be deployed in outdoor or semi-exposed environments, providing reliable performance under varying environmental conditions. With both ground stack and flown configuration options, it offers flexible integration within a wide variety of permanent sound reinforcement setups.
