x_var[mm]
| These limits are customarily indicated by Xmax, the maximum linear excursion. This value, measured in our catalogue according to AES2-1984 standard, corresponds to the reaching of 10% total harmonic distortion (THD) with a sinusoidal signal. Recent research shows that this method can yield ambiguous results and even different numerical values for the same loudspeaker. The main limit of this measurement is that it looks at the output signal instead of the physical features of the driver itself. On the contrary, the most up-to-date instruments for distortion analysis can measure the variations in loudspeaker parameters when they are fed with high-level signals. This way, an excursion limit can be fixed, beyond which the parameters variation becomes excessive. The "Xvar" value reported here, after the traditional "Xmax" value, is measured that way. Beyond this excursion limit, the magnetic field seen by the voice coil, or the total suspension compliance, or both, drop to less than 50% of their small signal value, producing high distortion levels, strong variations from small signal behaviour and power compression. The new technique yields different results from the standard measurement based on THD. B&C Speakers believes that this added information gives a more accurate and reliable description on loudspeakers behaviour in actual operating conditions. |

x_max_recalculated[mm]
| Unfortunately many loudspeaker manufactures use different equations for calculating x_max. The value, which is given here, is calculated by this equation*: x_max=(coil_height - magnetic_gap_depth) / 2 * if values coil_heigt and magnetic_gap_height are known |
|

n0_recalculated[%]
| The value n0_recalculated is calculated using the equation of Richard Small: 9,6 e ^ - 8 * fs ^ 3 * VAS / Qes With known values for n0 and n0_recalculated, you have the possibilty to compare these values. |
