Frequency SPL and Impedance Response Graphs
Loudspeaker Frequency and Impedance Response Graph
Measuring conditions for SPL
Driver mounting: Flush in infinite baffle
Microphone distance: 1.0 m
Input level: 2.83 VRMS
Smoothing: 1/6 oct.
Measuring conditions for impedance
Driver mounting: Free air, no baffle
Input signal: Stepped sine wave, semi-current-drive, nominal current 2 mA
Note 1 Measured in infinite baffle.
Note 2 Tested in free air (no cabinet).
Note 3 Measured using a semi-constant current source, nominal level 2 mA.
Note 4 Measured at 20 deg. 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 (www.linearx.com), involving parameters Krm, Erm, Kxm, and Exm.
Note 6 After burn-in specifications are measured 12 hours after exiting the transducer by a 20 Hz sine wave for 2 hours at level 6.3/8.9 VRMS (4/8 ohm version). The unit is not burned in before shipping.
