[. . . ] Furthermore, excellent loading is maintained to a low frequency of 1000 Hz. The flat-front design makes the 30W suitable for all modern boxed and clustered systems. [. . . ] The flat-front design makes the 30W suitable for all modern boxed and clustered systems. A special vaned waveguide throat detail gives the 30W unusually good high-frequency control, vertically, when compared to similar 2-inch-throat horn designs.
TransPlanarTM Constant-Directivity Horn
Architects' and Engineers' Specifications
The horn shall be of the constant-directivity type. It shall produce a horizontal beamwidth (6 dB-down angle) of 60 degrees, deviating no more that 30 degrees from this angle over the frequency range 2, 000 to 20, 000 Hz. It shall produce a vertical beamwidth of 40 degrees, deviating no more than 20 degrees from this angle over the frequency range 1, 600 to 20, 000 Hz. In addition, it shall provide useful acoustic loading at all frequencies above 1000 Hz. The horn shall be of hybrid fiberglass-and-zinc construction. Vertical beamwidth is maintained at 40° (+20°, -10°) over the range 1. 8 kHz to 20 kHz.
