(1) Please inquire about alternative impedances.
(2) Multiple units exceed published rating evaluated under EIA 426A noise source and test standard while in a free-air, nontemperature-controlled environment.
(3) The average output across the usable frequency range when applying 1 W/1 M into the nominal impedance. Ie: 2.83 V/8 ohms, 4 V/16 ohms. Fane response curves are measured under the following conditions:
All speakers are tested at 1 W/1 M using a variety of test set-ups for the appropriate impedance | LMS using 0.25" supplied microphone (software calibrated) mounted 1 M 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)
