* AES power rating (measured Power = E^/R, using Pink Noise with a crest factor of 6 dB and a band-limit of 60 to 600 Hz).

Low frequency limit is the 3 dB down point using the particular cabinet and the Thiele/Small parameters of the loudspeaker.

***

Measured in the free-fieid at 4.0 feet (1.2 m) on axis with one watt (Power = E^/R) of pink noise band-limited from 100 to 1000 Hz.
