Speaker Testing Method

1. Frequency Response

Use Pink noise t o t est t he speaker in t he anechoic chamb er,

adjust the level to make the speaker w ork at it s 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 m ake the speaker work at its rated

impedance and set the pow er output at 1W,then test the

sensitivity 1m aw ay from the speaker.

3. MAX.SPL

Use full range Pink noise which has been modified using

an EQ curve to t est the speaker in the anechoic chamber ,

increase the signal to make the speaker w ork at its

maximum pow er output level,t hen test the SPL1m away

from the speaker.

4. Rated Pow er

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

increase the signal for a cont inuous period of100 hours,

the rated pow er isthe pow er when the speaker will show

no visible or m easurable damage.
