Power calculated on minimum impedance. Loudspeaker tested in free air.(2)Continuous Power Handling is defined as 3dB greater than the AES rating.(3)Tested as per the EIA-426-A standard.(4)Measured on axis at 1W, 1m in 2pi anechoic environment.(5)Xmax derived from: (voice coil winding width-gap depth)/2.(6)Small signal parameters measured after unit subjected to pre-conditioning signal.
