KSL8 Line Array Speaker

The KSL8 loudspeaker, with 80° horizontal dispersion respectively, are unique among similar sized line array modules in providing consistent pattern control down to the lowest frequencies.

The geometry of two front facing 10" drivers and two (2) side firing 8" drivers couple and apply cardioid techniques, creating precise broadband directivity with significantly extended low frequency headroom towards the audience.  This low frequency extension and headroom is so effective that it negates the need for subwoofers flown behind or alongside the main hangs in many applications.  Midrange is delivered by a high sensitivity horn loaded with an 8" driver, while two (2) innovative, custom designed 3" voice coil HF drivers mounted on a wave shaping device provide the high frequency resolution and output.

More Information
Manufacturer d&b audiotechnik
  • Constant directivity behaviour over the entire operating range using cardioid techniques in the lower range
  • Exceptional broadband headroom
  • Patented SL-Series flying hardware and method enables rapid deployment of KSL8 and KSL12 arrays directly from the Touring cart in either compression or tension rigging modes
  • Requires only two amplifier channels; one channel drives the front facing 10" LF drivers, while the other amplifier channel drives the passively crossed over 8" side firing LF drivers, the 8" MF section and two HF drivers
  • ArrayProcessing optimizes the level and tonal balance over the complete audience listening area
  • For short arrays where ArrayProcessing is not required, two KSL loudspeakers can be linked and driven in the Arc / Line mode
  • Efficient cabling system and amplifier rack assemblies
  • Effective transport solutions
