Compact Full Range System

Where to Buy or Rent

DDX12 is part of the DDX series. Combining the ‘point-source’ benefits of coaxial designs with the consistent coverage of differential dispersion technology, DDX full-range systems project sound evenly front-to-back while exhibiting wide horizontal coverage close to the speaker — delivering ultimate fidelity and impact to all corners of the audience.


  • Multi-purpose, professional, passive full range systems
  • Coaxial Differential Dispersion technology achieves ‘point source’ performance and optimum coverage footprint across the audience plane
  • Compact, multi-angle enclosures for vertical and horizontal orientation and stage monitor use
  • Drivers can be rotated for vertical or horizontal operation by removing screw-free perforated steel grilles


  • Live sound reinforcement and portable systems
  • Stage monitors and sidefills
  • Theatre sound
  • Corporate AV events
  • Fixed installations in Government, Education, Museums, Hotels and hospitality

The DDX12 is a high-performance system designed for professional applications that require high output levels from a very compact enclosure. Its high-specification 12” (300mm) LF /1” exit HF coaxial differential dispersion driver delivers perfect sound across the audience over medium throw distances. The LF driver has a 2.5” (65mm) voice coil and efficient motor with an aluminium demodulating ring to minimise distortion, while the HF driver utilises a 1.75” (44mm) polyimide diaphragm and features a low-compression phase plug to reduce non-linearity.

The coaxial differential dispersion driver can be easily rotated for horizontal or vertical orientation depending on venue design requirements.

The DDX12 is constructed from durable plywood, finished with hard wearing black textured coating paint, and fitted with a screw-free steel grille, M8 inserts for a wall bracket and eyebolt suspension, plus a pole mount socket.

Ergonomic handles at the rear of the enclosure make for easy handling while maintaining clean lines.
