d&b audiotechnik has launched the 24S and 24S-D point source loudspeakers for permanent applications including houses of worship, multipurpose centres and sports venues.
These latest additions to the xS-Series all feature redesigned front grills. Differing only in horizontal dispersion, with 75° x 45° and 110° x 45° (h x v) respectively, the 24S and 24S-D house two 12-in LF drivers in a dipolar arrangement and a single hornloaded 1.4-in exit compression driver.
This HF horn is rotatable, meaning the 24S/24S-D can be mounted either vertically or horizontally. By separating the LF drivers, they achieve constant directivity control in the same plane as the dipole down to approximately 500 Hz.
With a frequency response extending from 55 Hz to 18 kHz, 24S and 24S-D are suitable for any full range application.
Housing a single 21-in driver in a bass-reflex design, the 21S-SUB can be operated in standard mode, to produce a frequency response of 35 Hz to 105 Hz, or as a supplement to other d&b subwoofers in INFRA mode, extending the LF performance to 33 Hz with an upper limit of 85 Hz.
In combination with the installation specific d&b amplifier, 30D, the 24S, 24S-D and 21S-SUB produce 138 dB SPL, 137 dB SPL, and 134 dB SPL respectively, and serve as a suitable alternative to a small multiple cabinet line array.
