Capable of more than 146dB peak output at 1m half-space, the ground-stack DSX powered and networked subwoofer achieves extremely high output levels from such a compact enclosure.

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.

Architectural Specifications

The loudspeaker shall be a self-powered, ground-stacked subwoofer. Its transducers shall consist of two 18” ultra-long excursion drivers in a bass reflex enclosure.

The loudspeaker shall incorporate a Class D amplifier module with onboard DSP. The amplifier shall deliver 6kW peak output to the transducers and include networking capabilities to enable remote control and system monitoring. Its power supply shall employ Power Factor Correction and operate from 100-240V, 50-60Hz AC.

Audio connectors shall be male and female XLR type and the AC power connector shall be an IEC309 CEE Form.

The loudspeaker shall be capable of forward and rear-facing operation to enable the construction of subwoofer arrays with specific directional properties determined by dedicated array control software.

The ground plane on-axis frequency response shall be 35Hz-150Hz +/- 3dB and the loudspeaker shall produce a maximum SPL of 146dB peak at 1 metre.

The loudspeaker enclosure shall be constructed from multi-laminate birch ply with a textured black polyurethane coating. The drivers shall be protected by a perforated steel grille.

Dimensions (W x H x D) shall be 1060mm x 595mm x 834mm (41.7in x 23.4in x 32.8in). Dimensions (W x H x D) with vent flap open shall be 1060mm x 595mm x 1027mm (41.7in x 23.4in x 40.4in).Weight shall be 122.2kg (269lbs).
