Important!
Please observe that these text files for download are actual measurements of the drivers measured in infinite baffle and without any enclosure. Measuring the drivers in a finite baffle (like the baffle of most speaker cabinets) and in any size of enclosure will lead to different response curves.

Tested in free air (no cabinet).

Note 3
|
Measured using a semi-constant current source, nominal level 2 mA.
|
|
Note 4
|
Measured at 25 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. This more accurate transducer model is described in a technical paper (PDF) here.
|
|
Note 6
|
After-burn-in specifications are measured at least 12 hours after exciting the transducer by a sine wave at the frequency of Fs for 2 hours at level 4/5 VRMS (4/8 ohm version). The unit is not burned in before shipping.
