(1) AES standard (2) Continuous power rating is measured in 125 lit enclosure tuned 50Hz using a 40 -400Hz band limited pink noise test signal applied continuously for 2 hours. (3) “Program power rating is measured as for ”2” above but 50% duty cycle .” (4) The peak power rating is based on a 6dB crest factor above the continuous power rating and represents the maximum permitted instantaneous peak power level over a maximum period of 10ms which will be withstood by the loudspeaker whituout damage. (5) Sensitivity represents the averaged value of acoustic output as measured on the forward central axis of cone , at distance 1m from the baffle panel, when connected to 2,83 V sine wave test signal swept

between 100Hz and 500Hz with the test specimen mounted in the same enclosure as given for 2 above. (6) Frequency range is given as the band of frequencies delineated by the lower and upper limits where the output level drops by 10 dB below the rated sensitivity in half space enviroment. (7) Power compression represents the loss of sensitivity for the specified power, measured from 50-500 Hz, after a 5 min pink noise preconditioning test at the specified power. (8) Thiele - small parameters are measured after the test specimen has been conditioned by 700 W AES power and represent the expected long term parameters after ashort period of use . (9) Linear Mat. Xmax is calculated as; (Hvc-Hg)/2 + Hg/4 where Hvc is the coil depth and Hg is gap depth.
