The DD6's Differential Dispersion technology provides an advanced
solution to the requirements of even coverage over wide angles and
medium throw distances.
Designed using Martin Audio's in-house BEM (Boundary Element Method)
tools, the short throw horizontal dispersion of the horn is 120°, narrowing
to 90° as throw increases. Vertically, the horn covers 60º, with greater
output above the horizontal centre plane.
The combination of narrower horizontal dispersion and greater output
above the horn's horizontal centre plane creates progressively more HF
output as the throw distance increases. The resultant dispersion pattern is
ideally suited to covering audiences located on flat or gradually sloping
surfaces.
