Why it mattered

  1. 01

    Low-mid directivity reduces masking in reverberant rooms.

  2. 02

    It brought SL-Series control to mid-size venues, alongside the GSL.

Professional reactions

Release-period reaction · 23 May 2019

Diener was struck by KSL’s control for its size and the even coverage from the arena pit to upper seats when paired with SL-SUBs.

Lance found KSL combined the deployment flexibility of a smaller rig with much of GSL’s power. He valued the combination of the cabinets and d&b’s software tools for both workflow and audience results.

Mitchell could make fuller-frequency in-ear mixes because he no longer had to compensate for as much sound spilling backwards from the PA. He also credited the cardioid subs with controlling low-end spill into monitor world.

Replacing V-Series side hangs with KSL gave Smith better side coverage and tighter, punchier low-end information. He found that particularly useful without flown subs.

Crowe credited the rear rejection of the combined GSL and KSL rig with keeping the stage quiet enough for consistent, clean in-ear mixes.

Clark found the full-range directivity of GSL mains and KSL sides improved coverage consistency while reducing sound behind the cabinets. He linked the quieter stage to cleaner microphone pickup.
