*** 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
