Frequency Response and Impedance curves
Topmost curve: Frequency Response on axis | Secondary curve: Frequency Response at 45° off axis
Power rating: Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.
Continuous power rating: Defined as 3dB greater than the AES rating.
Sensitivity: Measured on axis at 1W, 1m in 2π anechoic environment.
Xmax: 0.5*(Hvc-Hg) + 0.25*Hg
Parameters: Measured after unit subjected to pre-conditioning signal.
