Notes:
(1) Average over stated bandwidth. Measured in an IEC bae in an Anechoic Chamber
(2) Unweighted pink noise input, measured at 1 metre on axis
(3) Long term power handling capacity as dened in IEC 268-5 test
(4) The reference point for the reference axis (on-axis) is the centre of the bae.
