2.4. Dispersion characteristics
The graphs below show the horizontal dispersion angle over

frequency plotted using lines of equal sound pressure (isobars) at

–6 dB and –12 dB. The nominal dispersion is maintained above

600 Hz, while a useful horizontal dispersion control is achieved

down to 250 Hz.
