Notes
- The design and specifications are subject to change without notice for improvement.
- The specifications data were measured in an anechoic chamber, according to EN 54-24.
- Reference axis: The axis is on the centre horn mouth and perpendicular to the horn mouth.
- Reference plane: the plane is on horn mouth and perpendicular to the reference axis.
- Horizontal plane: the plane is containing the reference axis and perpendicular to the reference plane
Frequency response
A graph shows frequency response with decibels on the y-axis and frequency in Hertz on the x-axis. The line indicates a peak at 1 kHz and a gradual decrease towards higher frequencies.
Frequency response (1 W, 4 m)
Equalizer Required
To fit the frequency response to the EN 54-24 tolerance curve. Use an equalizer with the settings stated below to comply with the EN 54-24 requirements.
