Pink-noise signal, one watt calculated using E2/Zmin, 3.16-meter measurement distance referred to one meter. 2. On axis, one watt calculated using E2/Zmin, 3.16-meter measurement distance referred to one meter, low frequencies corrected for anechoic-chamber error. 3. This system rating patterned after the ANSI/EIA RS-426-A 1980 method where the test signal is pink noise with a 6-dB crest factor over the bandwidth of the system, with power calculated using E2/Re x 1.15, for eight hours (where E is the RMS test voltage and Re is the dc resistance of the woofer voice coil). 4. This measurement made under the same conditions as pressure sensitivity, but at rated power, and takes into account any power-com-pression effects due to nonlinearities in the system. 5. Distortion components invalid above 10 kHz. The distortion at any given frequency may be found by graphically taking the difference between the fund...
