High Power Coaxial Full-Range System

Blackline3 FX15 Loudspeaker
Where to Buy or Rent

The FX15 is a very high-power, coaxial two-way system designed for premium entertainment installations that demand the ultimate in sonic performance from a single enclosure.


  • High-output, coaxial passive two-way system
  • Coaxial Differential Dispersion™ technology
  • Elegant composite enclosure
  • User rotatable coaxial drive unit
  • Vertical and horizontal mounting options
  • Screw-free perforated steel grille


  • Small-medium live music clubs
  • Music bars
  • Nightclubs
  • Premium KTV
  • Infills in larger installations

Featuring a powerful 15” (380mm)/3” (75mm) voice coil LF drive unit, and a 1.4” (35mm) exit HF compression driver with a 3” (75mm) pure titanium diaphragm, it utilises unique Coaxial Differential Dispersion technology to deliver class-leading performance, fidelity and coverage consistency.

Coaxial Differential Dispersion™ technology delivers more consistent audience coverage than systems with conventional X° x Y° horns — projecting relatively more output to the rear of the audience to distribute sound evenly front-to-to-back, while having wide horizontal coverage close-up. In addition, the FX15 overcomes the high frequency ‘beaming’ associated with conventional coaxial devices — maintaining its dispersion pattern out to very high frequencies.

The attractive composite enclosure an be used in either horizontal (landscape) or vertical (portrait) orientation, with rotation of the coaxial driver easily accomplished by removing the screw-free, protective grille. Integral M8 inserts are provided for eyebolt suspension.

A full-range passive system, the FX15 may be used without a controller. However, the EQ and limiter functions of a controller such as the Martin Audio DX0.5 will maximise its capabilities. When used with a B18 or B218 subwoofer, crossover and EQ functions can be performed by the DX0.5 system controller.
