The new 24S and 24S-D point source loudspeakers from d&b audiotechnik are designed to for permanent install in venues. They are part of d&b audiotechnik’s xS series of loudspeakers. 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” LF drivers in a dipolar arrangement and a single hornloaded 1.4” 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. 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 a frequency response extending from 55 Hz to 18 kHz. For applications with bass heavy program material, the new 21S-SUB provides additional low end support from a conveniently small footprint. 

Housing a single 21” 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 the ideal 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, not to mention the budget benefits of the point source approach. 

With their purposefully designed larger cabinet volume, the 24S/24S-D deliver an improved low frequency reproduction for a truly full range point source, yet are modest enough to preserve sight lines and overcome rigging and placement restrictions.
