d&b audiotechnik SL-GSUB Large Format Cardioid Subwoofer

The d&b audiotechnik SL-GSUB is a large format cardioid subwoofer that complements the GSL and KSL Systems in ground stacked applications. Its actively driven 2 way bass reflex design houses three long excursion 21 inch neodymium drivers, two facing front and one to the rear, in independent chambers driven from separate amplifier channels, so the cardioid pattern reduces energy behind the system. Runners and matching top recesses keep stacks secure, and the side panels carry four recessed handles with four heavy duty wheels on the rear. Trianze Tech supplies the SL-GSUB in Dubai, Abu Dhabi and across the UAE and GCC.

Key Features:

  • Cardioid pattern rejects energy towards the rear
  • 3 x 21 inch neodymium drivers, two front and one rear
  • 33 to 84 Hz, INFRA mode 30 to 65 Hz
  • Up to 144 dB SPLmax with D80
  • Four recessed handles and four heavy duty rear wheels
  • Marine plywood with PCP finish, metal grills and water repellent fabric
