| Notes (*) |
| (1) |
Minimum Crossover Frequency require a 12 dB/oct or higher slope high-pass filter. |
| (2) |
Sensitivity is measured at 1 m on axis from the mouth of horn, averaged between 1 kHz and 4 kHz. |
| (3) |
AES Power rating is a test made for 2 hours with Pink Noise signal having a 6 dB Crest Factor from minimum crossover frequency. Power calculated on minimum impedance. Driver mounted on plastic horn. |
| (4) |
Program Power rating is defined as 3 dB greater than AES rating and is a conservative expression of the transducer ability to handle music program material. |
