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 is defined as 3dB greater than the AES rating.
Sensitivity measured on axis at 1W, 1m in 2Π anechoic environment.
Xmax is derived from: (voice coil winding width-gap depth)/2.
Small Signal Parameters are measured after unit subjected to pre-conditioning signal.
