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. X 2ft. baffle is built into the wall with the speaker mounted flush against a steel ring for minimum diffraction \| Hafler P1500 Trans-Nova amplifier \| 2700 cu.ft. chamber with fiberglass on all six surfaces (three with custom-made wedges).
****	BETA 8CX, 10CX, 12CX and ACOUSTINATOR� CX2008 are coaxial speakers with tweeter sold separately. Published Usable Frequency response contingent upon use of APT 50 HF Driver.
