* Please consult
eminence.com for specifications of models with 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”
