Frequency SPL and Impedance Response Graphs
Loudspeaker Frequency Response Graph
Measuring conditions, SPL
Driver mounting: Flush in infinite baffle
Microphone distance: 1.0 m
Input level: 2.83 VRMS
Smoothing: 1/6 oct.
Loudspeaker Impedance Response Graph
Measuring conditions, impedance
Driver mounting: Free air, no baffle
Input signal: Stepped sine wave, semi-current-drive, nominal current 2 mA
Note 2: Tested in free air (no cabinet, no baffle).
Note 3: Measured using a semi-constant current source, nominal level 2 mA.
Note 4: Measured at 25°C.
Note 5: It is generally a rough simplification to assume that loudspeaker transducer voice coils exhibit the characteristics of an inductor. Instead it is a far more accurate approach to use the more advanced model often referred to as the "Wright empirical model", also used in LEAP-4 as the TSL model, involving parameters Krm, Erm, Kxm, and Exm.
Note 6: Calculated as the area inside the middle of the surround
Note 7: Determined by physical weighing of the moving parts including the inner half of the surround.
