ASD:1001 HF Drivers
** Multiple units exceeded published power rating evaluated under EIA-426B specication while mounted on Eminence’s H290 or H290S horn in a non-temperature controlled environment.
*** The average on axis output across the entire usable frequency range when mounted to the H290 or H290S horn and applying 1W/1m into the nominal impedance, i.e. 2.83V/8Ω, 4V/16Ω. 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 horn front mounted | Carver PM-120 amplier | 2700ft3 chamber with berglass on all six surfaces (three with custom-made wedges).
