Directivity

The directional characteristics of the HP66 were measured in Electro-Voice’s large anechoic chamber using a stock Electro-Voice® DH1A. The test signal was one-third-octave filtered pink-noise at the frequencies indicated. A full spherical measurement system was used. All directional information was measured at 6.1 meters (20 feet) from the horn.

This illustrates the total directivity of the HP66. The directivity factor Rθ	This shows the horizontal and vertical beamwidths. Beamwidth is the
(Q) is the relative value at a point of the HP66 when compared to an	angle at which the horizontal and vertical polar responses have
ideal spherical response. The directivity index Di is calculated by	decreased in level by 6 dB when compared with the axial frequency
Di=10log10Rθ.
