    ** 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(TM) CX2008 are coaxial speakers with tweeter sold separately. Published Usable Frequency response contingent upon use of APT 50 HF Driver.

    Important Note

    Watts: The guaranteed long term power rating throughout the usable frequency range of the speaker.

    (Translation: the speaker will operate continuously at any frequency within the speakers specified frequency range when driven at this power. The "Watts" rating is similar to RMS, but is really more indicative of long term thermal capability.)

    Music Program: The speaker will safely and reliably handle the varying frequencies of musical content at this power rating. The "Music Program" rating is more indicative of what you can expect in the real world with the speaker operating within the appropriate enclosure reproducing music or vocal audio program.
