  FOOTNOTES
  
  *: Please consult www.eminence.com for specifications of models with alternative impedances.
  **: Multiple units exceed published rating evaluated under EIA 426A noise source and test standard while in a free-air, non-temperature controlled environment.
  ***: The average output across the usable frequency range when applying 1W/1M into the nominal impedance. Ie: 2.83V/8ohms, 4V/16ohms. Eminence response curves are measured under the following conditions: All speakers are tested at 1w/1m using a variety of test set-ups for the appropriate impedance " LMS using 0.25" supplied microphone (software calibrated) mounted 1m from wall/baffle " 2ft.
