How our loudspeakers are measured
1. Power Handling
Full bandwidth pink noise, meeting the IEC Standard
2. Sensitivity
Full bandwidth pink noise is applied to the loudspeaker with its active equalization curve and amplified to a level at the loudspeaker terminals corresponding to 1 watt as referenced to the nominal impedance. The average sound pressure level
3. Maximum SPL
Full bandwidth pink noise is applied to the loudspeaker with its active equalization curve and amplified to a level at the loudspeaker terminals corresponding to the
4. Frequency Range
Sine waves are injected into the loudspeaker and the level is adjusted to 1 watt, as referenced to the nominal impedance, and the level measured at 1meter. Resulting graph is smoothed by 0.05
