Emininece Speaker Tech Notes

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.

Eminence Speaker frequency response curves are an average of multiple units measured while applying 1W/1m into the speakers’ nominal impedance (e.g. 2.83V/8Ω, 4V/16Ω, etc.). All speakers are measured in a temperature controlled environment using monthly calibrated LMS software with supplied 0.25" microphone mounted on axis 1m distance from baffle. 2 ft. x 2 ft. baffle is flush with anechoic wall and speaker is rear mounted against a thin steel ring for minimum diffraction. Measurements performed using monthly calibrated Yamaha P3500S amplifier and a 2700 cubic foot anechoic chamber with custom made fiberglass surface treatments. Measurements below 200Hz are tail corrected to compensate for chamber volume. Compression drivers measured using a 2ft x 2ft baffle flush with anechoic wall and horn front mounted.

Please note: BETA 8CX, 10CX and 12CX are coaxial speakers with tweeter sold separately. The data for these coaxial woofers was calculated with the ASD:1001 driver screwed into the woofer, but not active.
