DIMENSIONS mm (in.)
(1) Program power is defined as 3 dB greater than AES Power. (2) Tested for two hours using a
continuous, band-limited pink noise signal as per AES 2-1984 Rev. 2003. Loudspeaker tested
in free air. (3) From T/S parameters, measured with Klippel DA LPM module. (4) The Xmax is
calculated as: (Hvc - Hg)/2+ Hg/4. Hvc is the voice coil height and Hg the gap height. (5) The
Xmech is calculated as: (Hvc - Hg)/2 +(Hg-2). Hvc is the voice coil height and Hg the gap height.
(6) Thiele-Small parameters are measured after preconditioning: a) at 20°C- 22°C, 50% humidity
for 2 hours; b) by Klippel LSI measurement.
