Frankfurt, Germany (April 11, 2018)—At Prolight + Sound 2018, d&b audiotechnik has officially launched its new SL-Series, GSL System as its new flagship. The result of four years of development, the system sports new drivers, new cabinet geometry and flexible mechanics, according to the company. The resulting GSL System was created specifically for use in covering large arenas, stadiums and festivals.
The GSL8 and GSL12 loudspeakers, with 80˚ and 120˚ horizontal dispersion respectively, reportedly provide consistent pattern control down to 45 Hz. According to d&b, the geometry of two front facing 14” drivers and two side firing 10” drivers create such low frequency extension and headroom that flown subwoofers are usually unnecessary as a result.
Mid-range is delivered by a high sensitivity horn loaded with a 10” driver, while three custom-designed 3.4” diaphragm HF drivers mounted on a wave shaping device provide the high frequency output.
Each loudspeaker is driven in 2-way active mode by the d&b D80 amplifier: one channel powers the 14” drivers, with all other components passively crossed over and powered by a second channel.
The SL-SUB and SL-GSUB complement the low end with two forward facing 21” drivers and a single, rear facing 21” driver delivering the cardioid dispersion. The SL-SUB can be flown, while the SL-GSUB is designed for ground stacked applications.
The SL-Series brings a patented combination of tension and compression modes and procedures to the d&b three-point rigging. The compression mode enables a straight array to be flown from Touring carts, and a hoist or hand winch then curves the array to the defined splay angles. Designed to fit within standard shipping container and truck sizes, touring carts with covers transport four GSL8 or GSL12 loudspeakers, or three SL subwoofers. The Touring rack assembly, housing six D80 amplifiers, also contains a DS10 Audio network bridge, the MC24 multicore system and provides PoE for the d&b ArraySight inclinometer.
