 NOTES:

1. AES standard(50~500Hz)

2. Program Power is defined as 3 dB greater than the nominal power handling.

3. Sensitivity is measured at 1W input on rated impedance at 1m on axis  and  

    averaged between 100Hz and 400Hz.

4. Frequency range is defined as the band of frequencies  delineated  by the lower

   and upper limits where the output level drops by 10dB below the rated sensitivity.

5. The maxinum linear excursion is calculated as: (Hvc-Hg)/2+Hg/4 where Hvc is    

    The voice coil depth  and Hg is the gap depth.

6. Vb: Net internal volume of box after subtracting the volume of internal objects.
