* Please consult www.eminence.com for specifications of models with alternative
impedances.
** Multiple units exceed published ratings evaluated under EIA 426A specification while
tested in a free-air, non-temperature-controlled environment.
*** The average 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 | 2 ft. x 2 ft. baffle is built into the wall with
the speaker mounted flush against a steel ring for minimum diffraction | Carver PM-120
amplifier | 2700 cu. ft. chamber with fiberglass on all six surfaces (three with custom-
made wedges).
**** BETA 8CX, 10CX, and 12CX are coaxial speakers with tweeter sold separately. Published
usable frequency response contingent upon use of ASD:1001 HF Driver.
***** Multiple units exceeded published ratings evaluated under EIA-426A or AES specification
while mounted on Eminence’s H290, H290S, or H2EA horn in a non-temperature-
controlled environment.
******The average on axis output across the entire 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 horn front mounted | Carver PM-120 amplifier | 2700 cu.ft. chamber
with fiberglass on all six surfaces (three with custom-made wedges).
