d&b audiotechnik SL-GSUB

d&b audiotechnik SL-GSUB are cardioid subwoofers to compliment the GSL and KSL Systems. The SL-SUB rigging hardware allows columns of up to 14 cabinets to be flown while the SL-GSUB is intended for ground stacked applications only. Both 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.
