4 Optimized coverage HF horn has a wider dispersion in the near-field and narrower in the far field. HF horn has a 40° vertical coverage and a radiation axis aiming 15° down from the horizontal plane. At an upper vertical threshold (5° up from horizontal plan) speaker has a horizontal coverage of 60°. At a lower vertical threshold (35° down from horizontal plan) speaker has a horizontal coverage of 90°
