Visual Sound DD6 扬声器

Martin Audio Limited","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 60°, 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
