Loudspeaker

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

nominal impedance. The average sound pressure

level (dB-SPL) is measured at 1 meter from the

speaker in an anechoic environment.

3. Maximum SPL

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 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 refer-

enced to the nominal impedance, and the level

measured at 1 meter. Resulting graph is

smoothed by 0.05 octave band.
