Materials of Construction
Please inquire about alternative impedances.
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/bafe | 2ft. X 2ft. bafe is built into the wall with the speaker mounted ush against a steel ring for minimum diffraction | Haer P1500 Trans-Nova amplier | 2700 cu.ft. chamber with
