NOTES:
1. AES standard(40~400Hz)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 50Hz and 500Hz.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.High quality 18 inch subwoofer speaker MW18-100/audio speaker/outdoor new product
