Description

  • The SL-SUB are cardioid subwoofers to compliment the KSL Systems.  The subwoofers are actively driven 2-way bass-reflex designs housing three long excursion 21″ neodymium drivers. 
  • Two drivers face to the front while one radiates to the rear. The front and rear facing drivers operate in independent bass reflex chambers and are driven from separate amplifier channels. 
  • The cardioid dispersion pattern reduces unwanted energy behind the system, resulting in less excitation of the reverberant field to deliver highly accurate low frequency reproduction. The frequency response extends from 30 Hz to 90 / 65 Hz.
