NOTE:
(1). Tested for two hours using a continuous band-limited pink noise signal as per AES 2-1984 Rev.
2003.
(2). Loudspeaker tested in free air.
(3). T/S Parameters, measured and cross validated with two different modules.
(4). Its measured after pre-conditioning at , 50% 25°C- 30°C humidity for 2 hours.
(5). Xmax is calculated as:
(Hvc – Hg) / 2 + Hg/4. Hvc is the voice coil height and Hg is the height of gap.
