OTHERS

(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 LMS 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) TheXmech 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 LMS LSI measurement.
