Specifications
Audio
a
Measured at distances of 4m and 8m, in free field and on ground plane. Sensitivity is calculated based on measured
SPL response averaged in the 200 Hz-3 kHz range and scaled back to 1 m.
b
AES refers to the AES2-2012 standard. IEC refers to the IEC 60268-5 standard. Maximum continuous SPL is
calculated based on sensitivity and AES power handling. IEC short-term power is tested using IEC pink noise with a
9 dB crest factor. The crest factor was specifically increased to reflect real life parameters of digital cinema
soundtracks. Maximum peak SPL is calculated using peak voltage during the IEC short-term power test.
c
Averaged in the 500 Hz-16 kHz range, at -6 dB. Screen scattering effect results in a slight increase of coverage at
high frequency.
