(1) AES power is determined according to AES2-1984 standard. (2) Program power rating is measured in 125 lit. enclosure tuned at 50Hz using a 40-400 Hz band limited pink noise test signal applied for 2 hours and with 50% duty cycle. (3) 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 2.83V sine wave test signal swept between 100 Hz and 500 Hz with the test specimen mounted in the same enclosure as given for 2 above. (4) Thiele - Small parameters are measured after the test specimen has been conditioned by 1 hour 20 Hz sine and represent the expected long term parameters after a short period of use. (5) Linear Mat. Xmax is calculated as; (Hvc-Hg)/2 + Hg/4 where Hvc is the coil depth and Hg is gap depth.
