Recommended amplifier power

Rated impedance

Measured at distances of 4 m and 8 m, in free field and on ground plane. Sensitivity is calculated based on the

measured SPL response averaged in the 200 Hz-3 kHz range and scaled back to 1m.

AES refers to AES2-2012 standard. IEC refers to 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.

Averaged in the 500 Hz -16 kHz range at -6 dB.
