Speaker Testing Method

1. Frequency Response

Use Pink noise to test the speaker in the anechoic chamber, adjust the
level to make the speaker work at its rated impedance and set the output
power at 1W, then test the frequency response 1m away from the

speaker.

2. Sensitivity

Use full range Pink noise which has been modified using an EQ
curve to test the speaker in the anechoic chamber, increasing the

signal to make the speaker work at its rated impedance and set the

power output at 1W, then test the sensitivity 1m away from the

speaker.

3. MAX.SPL

Use full range Pink noise which has been modified using an EQ
curve to test the speaker in the anechoic chamber , increase the
signal to make the speaker work at its maximum power output
level, then test the SPL1m away from the speaker.

4. Rated Power

Use Pink noise to the IEC#268-5 standard to test the speaker,

increase the signal for a continuous period of 100 hours, the

rated power is the power when the speaker will show no visible

or measurable damage.
