* 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, nontemperature-controlled environment.
*** The average output across the usable frequency range when applying 1W/1m into the nominal impedance. ie: 2.83 V /8 ohms, 4 V /16 ohms. 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 | 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™ CX 2008 are coaxial speakers with tweeter sold separately. Published Usable Frequency response contingent upon use of APT 50 HF Driver.
***** Multiple units exceeded published rating evaluated under AES 500 and AES 800 noise sources and test standards while mounted on Eminence's TI-2000 horn in a nontemperature-controlled environment.
****** The average on axis output across the entire usable frequency range when applying 1W/1m into the nominal impedance while mounted on a Community SH 494 horn measured with: LMS (software calibrated) using a 0.25" [6.4mm] supplied microphone mounted 1m from horn mouth, Hafler P1500 Trans-Nova amplifier, 2700 cu.ft. chamber w/fiberglass on all six surfaces (three with custom made wedges). Plane-wave tube response and impedance curves measured with LMS on a 0.75" [19.1mm] diameter tube with adapter to allow for smooth transition to throat diameter and 1W/1m into nominal impedance.
