| Comparison: Constant Directivity Horn with Complex Conic Wave-Guide Horn |
One problem conventional horns exhibit occurs at
lower frequencies, where the wavelength of the sound waves exceeds any
of the horn dimensions. As illustrated below (orange ellipse in the left
graphic), conventional horns exhibit a phenomena known as "pattern
flip". The coverage pattern rotates 90° or "flips"
compared to its dominating (yellow) mid frequency pattern. |

A second problem with conventional horns occurs at
higher frequencies, where the dimensions of the horn are greater than
the wavelength. Obviously, the diagonals of any rectangular shaped horns
are longer than its sides. The greater dimensions impose greater control.
This problem is illustrated at left by the blue "clover leave"
pattern. By contrast, the ComplexConic horn illustrated at right above, demonstrates much improved uniformity in coverage. Note: Not only do ComplexConic horns improve on the uniformity of coverage over a larger range of frequencies, they also deliver noticeably cleaner sound. |
