How our Loudspeakers are
Measured
PC 040806
1. Power handling
Full-bandwidth pink noise, meeting the IEC
Standard #268-5, is applied to the loudspeaker
PC 041865
and amplified to a level at the loudspeaker
PC 041866
terminals corresponding to the power handling
PC 041867
of the loudspeaker. The loudspeaker must show
PC 041868
no visible damage or measurable loss of perform-
ance after 100 hours of continuous testing.
2. Sensitivity
PN 295891-001
Full-bandwidth pink noise is applied to the loud-
PN 295891-002
speaker with its active equalization curve and
PN 299564
amplified to a level at the loudspeaker terminals
PN 299565
corresponding to 1 watt, as referenced to the
PN 299558
nominal impedance. The average sound pressure
PN 299559
level (dB-SPL) is measured at 1 meter from the
PN 303038-001
speaker in an anechoic environment.
PN 303038-002
3. Maximum SPL
PN 299568-001
Full-bandwidth pink noise is applied to the loud-
PN 299568-002
speaker with its active equalization curve and
PN 299562
amplified to a level at the loudspeaker terminals
PN 299563
corresponding to the long-term rated power
handling of the speaker. The average sound
pressure level (dB-SPL) is measured at 1 meter
from the speaker in an anechoic environment.
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 1 meter. Resulting graph is smoothed by 0.05
octave-band.
