Speaker Testing Method

1. Frequency response

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

2. Sensitivity

Use  full  range  Pink  noise  which  was  modified  by  EQ  curve  to 
test  the  speaker  in  the  anechoic  room,  enlarge  the  signal  to 
make  the  speaker  work  at  its  rated  impedance  and  the  power 
output is 1W, then test the sensitivity  1m  away from the speaker.

3. MAX.SPL

Use full range Pink noise which was modified by EQ curve to
test the speaker in the anechoic room, enlarge the signal to 
make the speaker work at its instant power output level, then 
test the SPL  1m  away from the speaker.

4. Rated Power

Use the pink noise according to IEC#268-5 to test the speaker, 
enlarge the signal for continuous 100hours, the rated Power is 
the  power  when  the  speaker  will  not  incur  hot  damage  or 
mechanics damage.
