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).

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.
