| ·EIA power is measured with 6dB crest factor continuous pink noise in 8 hours | ||
| duration. | ||
| ·Max power is defined as 3dB higher than the nominal rating. | ||
| ·Sensitivity is measured as one meter at 2V and 4 ohm nominal impedance. | ||
| ·All measurement of the speaker is done after a sufficient high level of 20Hz sine | ||
| wave test. | ||
| ·Xmax=[(Winding Depth-Magnetic Gap Depth)/2] | ||
