Frequency Response and Impedance Curves
Black: LF response curve | Red: HF response curve
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.
HF Power Rating:Tested for two hours on plane wave tube using a continuous, band limited pink noise signal as per AES standard. Power calculated on minimum impedance
HF Continuous Power Handling is defined as 3dB greater than the AES rating
