Description

KS28 is the matched sub for almost every K-family build we do — eight cabinets is enough for a flown four-per-side cardioid array under a Kara II or K2 main, or a ground-stacked end-fire array for an outdoor festival.

Comes with LA12X amplification, all flying hardware, and a tech who has built this rig with us a dozen times. Specify L-Acoustics Soundvision file with the booking and we will pre-tune the array before load-in.


What we hire it for

  • Sub-base for any K-Series or Kara II main PA
  • Flown cardioid sub array (4-per-side typical)
  • Ground-stacked end-fire array for outdoor festival
