d&b audiotechnik GSL12 Loudspeaker


The GSL8 and GSL12 loudspeakers are acoustically matched and constructed to be mechanically compatible sharing the same vertical directivity, size, footprint, weight, rigging and driver complement. The 2-Way active design features two 14″ LF drivers, two side firing 10” LF drivers combining in a geometry that create unprecedented low frequency headroom which couples towards the front to increase the LF output and cancels towards the rear by applying cardioid techniques. The driver compliment is completed by one horn loaded 10″ MF driver and three custom designed 1.4” exit HF drivers with 3.4” voice coils in a compact format mounted to a dedicated wave shaping device.

The symmetrical arrangement of the neodymium LF drivers around the centrally mounted coaxial MF and HF components allows a smooth overlap of the adjacent frequency bands in the crossover designs with the 14” LF drivers being driven from one amplifier channel, while all other components are passively crossed over and driven from a second amplifier channel.

The 80° horizontal directivity pattern of the GSL8 is seamlessly maintained down to 45 Hz and its high output capability can cover a distance range of over 100 m (330 ft), depending on the climatic conditions. The GSL12 has a wider horizontal dispersion pattern of 120° which is also maintained down to 45 Hz.
