The GSL12 produce a full-range constant directivity behaviour, using a combination of technologies which include cardioid techniques in the lower range. This behaviour rejects energy towards the rear, significantly reducing excitation of the reverberant field, which results in minimized reflections indoors, a superior working environment onstage and lower sound emissions to unnecessary areas outdoors.

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 GSL loudspeakers are acoustically matched and constructed to be mechanically compatible sharing the same vertical directivity, size, footprint, weight, rigging and driver complement.
