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 on axis output across the usable frequency range when applying 1W/1m into the nominal impedance, i.e. 2.83V/8Ω, 4V/16Ω. 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 x 2ft baffle is built into the wall with speaker mounted flush against a steel ring for minimum diffraction \| Carver PM-120 amplifier \| 2700ft3 chamber with fiberglass on all six surfaces (three with custom-made wedges).
