1. AES standard practice with high pass filter set at specified lower limiting frequency for two hours.

2. Sensitivity is measured with applied pink noise RmS Voltage set to 2.83V for nominal 8 ohms impedance and mesurment taken at 1 meter from mouth of horn. Average SPL taken between 1000 Hz to 19 kHz .

3. Frequency range is defined as measured frequency-10dB to rated sensitivity.
