d&b launches new permanent install loudspeakers

d&b audiotechnik has added the 24S and 24S-D point source loudspeakers to its xS-Series, designed for permanent install applications including nightclubs, live performance venues, and houses of worship, as well as multipurpose centres and sports venues.

The new models upgrade the performance level for d&b’s installation specific point sources, and along with the arrayable xA-Series, all feature redesigned front grills. “The 24S, 24S-D and 21S-SUB are designed to set and forget. They meet the exact day to day demands of permanent installation with minimum fuss and maximum reliability,” explained Wolfgang Schulz, product manager of installation products at d&b.

Differing only in horizontal dispersion, with 75° x 45° and 110° x 45° (h x v) respectively, the 24S and 24S-D house two 12in LF drivers in a dipolar arrangement and a single hornloaded 1.4in 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 500Hz. The result is a powerful single box solution that avoids the transmission of energy into the reverberant field, and increasing gain before feedback when working with open microphones. The 24S and 24S-D have frequency response extending from 55Hz to 18kHz, suited to a variety of full range applications.

The new 21S-SUB provides additional low end support from a small footprint. Housing a single 21in driver in a bass-reflex design, the 21S-SUB can be operated in standard mode, to produce a frequency response of 35Hz to 105Hz, or as a supplement to other d&b subwoofers in INFRA mode, extending the LF performance to 33Hz with an upper limit of 85Hz.

In combination with the installation specific d&b amplifier, 30D, the 24S, 24S-D and 21S-SUB produce 138dB SPL, 137dB SPL, and 134dB SPL respectively, and serve as an alternative to a small multiple cabinet line array. The flexibility of the system makes it ideally suited whenever ceiling height and amplifier channel count make a line array inappropriate.
