     Eminence response curves are measured under the following controlled test 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 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)
