Where to Buy or Rent

DDX15 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

Ideal for medium-to-large rooms, the DDX15 is a very high-power, passive two-way system designed for professional portable applications and installations that demand the ultimate in sonic performance from a single enclosure.

It combines very high output capability with exceptional fidelity and coverage consistency. Its coaxial differential driver unit comprises a powerful 15” (380mm)/3” (75mm) voice coil LF driver and a 1.4” (35mm) exit HF compression driver with a 3” (75mm) pure titanium diaphragm.

Its protective steel grille is a spring-fit into the sides of the enclosure for easy access to rotate the HF horn. The symmetrical, multi-angle enclosure is manufactured from durable plywood and coated in textured black paint. It is fitted with 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.
