Note

(1)Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.

(2)Measured on axis at 1W, 1m in 2pi anechoic environment.

(3)Xmax derived from: (voice coil winding width-gap depth)/2.

(4)Small signal parameters measured after unit subjected to pre-conditioning signal.
