How our Loudspeakers are
Measured
1. Power handling
Full-bandwidth pink noise, meeting the IEC
Standard #268-5, is applied to the loudspeaker
and amplified to a level at the loudspeaker
terminals corresponding to the power handling
of the loudspeaker. The loudspeaker must show
no visible damage or measurable loss of perfor-
mance after 100 hours of continuous testing.
2. Sensitivity
Full-bandwidth pink noise is applied to the loud-
speaker with its active equalization curve and
amplified to a level at the loudspeaker terminals
corresponding to 1 watt, as referenced to the
PC 323205-0010
nominal impedance. The average sound pressure
level (dB-SPL) is measured at 1 meter from the
PC 041864
speaker in an anechoic environment.
3. Maximum SPL
PC 041993
Full-bandwidth pink noise is applied to the loud-
speaker with its active equalization curve and
PC 041862
amplified to a level at the loudspeaker terminals
corresponding to the long-term rated power
handling of the speaker. The average sound
PC 041863
pressure level (dB-SPL) is measured at 1 meter
PC 323207-0210
from the speaker in an anechoic environment.
4. Frequency range
PC 326668-0010
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
PN 299570
at 1 meter. Resulting graph is smoothed by 0.05
PN 299571
octave band.
PN 324015-001S
