free air.  
2 Power on Continuous Program is defined as 3 dB greater than the Nominal rating.  
3 Applied RMS Voltage is set to 2.83V for 8 ohms Nominal Impedance. Average  
SPL from 200 to 3500 Hz.  
4 Thiele-Small parameters are measured after a high level 20 Hz sine wave precon-  
ditioning test.
