Product Description for the Eminence ALPHA-6A

Very versatile and great sounding pro audio midrange in a sealed cabinet, or as a midbass in a vented satellite enclosure.

Multiple units exceed published ratings evaluated under EIA 426A specification while tested in a free-air, non temperature-controlled environment. Multiple compression drivers exceeded published ratings evaluated under EIA -426A or AES specification while mounted on Eminence’s H290, H290S, or H2EA horn in a non-temperature-controlled environment.

The average output across the usable frequency range when 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/baffle | 2 ft. x 2 ft. baffle is built into the wall with the speaker mounted flush against a steel ring for minimum diffraction | Yamaha P3500S amplifier | 2700 cu. ft. chamber with fiberglass on all six surfaces (three with custom-made wedges). Compression drivers were tested using a 2ft x 2ft baffle built into the wall with horn front mounted.
