Exceptional Fidelity And Coverage Consistency

Martin Audio's CDD15 (MAU-CDD15B) High-Output Coaxial Differential Dispersion System is a very high-power, passive two-way system designed for installations in medium-to-large rooms 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 drive 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. The visually-distinctive composite enclosure can be used in either horizontal (landscape) or vertical (portrait) orientation, with rotation of the driver easily accomplished by removing the screw-free, protective grille. The CDD15 can be suspended by eyebolts or by means of an optional horizontal yoke.


  • High-Output, CDD™ Passive Two-Way System
  • Coaxial Differential Dispersion™ Technology
  • Elegant UPM Formi Composite Enclosure
  • User-Rotatable Coaxial Drive Unit
