FOOTNOTES
* Please consult 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.
