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.
