The directivity index (DI) of the H9500 horn is shown in Figure

5.The smoothly rising DI is a consequence of the gradual narrowing of the vertical dispersion angle above 2 kHz and contributes to the overall flatness of the high-frequency response of the system.

Frequency (Hz)

Overall system on-axis pressure response and impedance are shown in Figure 6. The contributions of the paralleled low- frequency sections and the high-frequency section are shown individually along with their acoustical summation. The overall slopes in the crossover region are a combination of electrical (network) and acoustical response.

Figure 6. On-axis response of M9500. Individual contributions of paralleled low-frequency transducers and high-frequency section are shown, along with their summation. The impedance curve is also given, showing a minimum value of 3 ohms in the 100 Hz range.

The second and third harmonic distortion of the system is shown in Figure 7. Here, the system is driven with sine wave input to produce an output of 96 dB Lp at a distance of 1 meter. An output of 96 dB with a sine wave input corresponds to extremely high system output with wide band program material. Distortion curves have been raised 20 dB, and the val- ues seen here lie well below 1% for the lowest frequencies up to 4.5 khz, reaching a value of only 1.6% at 10 kHz. Not many loudspeakers can demonstrate such low levels of distortion as shown here.
