(1) Aes standard (2) Continuos power rating is measured in 25 lit enclosure tuned 65Hz using a 60 -2000Hz 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 continous power rating and represents the maximum permitted instantaneous peak power level over a maximum period of 10ms which will be withstood by the louds.(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 signalswept between 500Hz and 25.(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)Thiele - small parameters are measured after the test specimen has been conditioned by 280 W aes power and represent the expected long term parameters after a short period of use .(8)Matematical xmax parameter represents the voice coil depth less the gap depth .(9) Linear Mat. Xmax is calculated as; (Hvc-Hg)/2 + Hg/4 where Hvc is the coil depth and Hg is gap depth.(10)Continuos program power is defined as 3 dB greater than continuous pink noise and is a conservative expression of the transducer ability to handle music program material. (11)sensitivity is measured on 1W input on rated impedance at 1m on axis from the mouth of the woofer and averaged in 3kHz band.
