Technical Specification 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 at 1W, then test the frequency response power

1m away from the speaker.

2. Sensitivity

Use full range Pink noise which has been modified using

an EQ speaker in the anechoic chamber, curve to test the

increasing the work at its rated signal to make the speaker

impedance and set the the power output at 1W, then test

sensitivity 1m away from the speaker.

3. MAX.SPL

Use full range Pink noise which has been modified using

an EQ speaker in the anechoic chamber , curve to test the

i n c r e a s e t h e wo r k a t i t s s i g n a l t o m a k e t h e s p e a k e r

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 of100 hours,

the rated power is the power when the speaker will show

no visible or measurable damage.
