Performance Charts
The following charts illustrate the acoustic performance of the Sonance PS-C43RTLP speaker:
1 Meter On-Axis Frequency Response
This chart shows the speaker's frequency response measured at 1 meter on axis. It indicates a relatively flat response from approximately 75 Hz to 20 kHz.
Beamwidth vs Frequency
This graph illustrates the beamwidth of the speaker at different frequencies, showing how the sound disperses.
Impedance vs Frequency
This chart displays the speaker's impedance across the frequency range, with a nominal impedance of 8 Ohms.
Directivity Index vs Frequency
This graph shows the directivity index of the speaker, indicating how focused the sound is at different frequencies.
1 Meter Horizontal Frequency Response
This chart presents the horizontal frequency response measured at 1 meter, showing the response at various off-axis angles (0°, 10°, 20°, 30°, 40°).
Polar Patterns
The polar patterns illustrate the directivity of the speaker at various frequencies. Each pattern shows the sound pressure level (dBR) at different angles relative to the speaker's axis.
Polar Pattern (Example 1)
This polar pattern shows the speaker's directivity at a specific frequency, with data points for different angles.
Polar Pattern (Example 2)
Another polar pattern illustrating the speaker's off-axis performance.
Polar Pattern (Example 3)
This polar pattern demonstrates the speaker's dispersion characteristics.
Polar Pattern (Example 4)
