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 aluminium 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.
