Description

Features

  • Ultra-high output subwoofer with onboard Class D amplification. DSP and networking
  • Two reflex-loaded 18” (450mm)/4” (100mm) drivers perfectly balance low frequency extension and impact
  • Switched mode power supply with PFC (Power Factor Correction) and global mains voltage operation
  • Forward or rear-facing operation
  • Designed to meet IP24 environmental rating

Applications

  • Outdoor festivals
  • Arenas and theatres
  • Concert halls
  • Premium fixed installations

The DSX’s high output capability is achieved by combining state-of-the-art driver technology with an onboard Class D amplifier module which can deliver 6kW peak power.

Its two reflex-loaded 18” (450mm)/4” (100mm) drivers perfectly balance low frequency extension and impact.

Forward output as well as rear rejection can be optimised to achieve coverage where required and cancellation elsewhere.

A flying version, the DSX-F can be flown alongside or at the top of MLA Compact arrays, as well as being ground-stacked. The ground-stack DSX can be upgraded to a DSX-F by an easy-to-fit accessory kit.
