GA-SC64
Tones of 1964 still ring true in this
vintage voiced speaker by seasoned
amp guru George Alessandro. Wellbalanced from top to bottom, the
GA-SC64’s warm, dynamic character
lends itself to vintage amps as well
as modern gain and distortion.
The traditional build materials
offer warmth, dynamics, low note

mission statement
footnotes
Eminence is dedicated to providing the best Quality, Value and Service
to meet our customers’ needs.
* Please consult www.eminence.com for specifications of models with alternative
impedances.
** Multiple units exceed published ratings evaluated under EIA 426A specification while
tested in a free-air, 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 | Carver PM-120
amplifier | 2700 cu. ft. chamber with fiberglass on all six surfaces (three with custommade wedges).
**** BETA 8CX, 10CX, and 12CX are coaxial speakers with tweeter sold separately. Published
usable frequency response contingent upon use of ASD:1001 HF Driver.
***** Multiple units exceeded published ratings evaluated under EIA-426A or AES specification
while mounted on Eminence’s H290, H290S, or H2EA horn in a non-temperaturecontrolled environment.
******The average on axis output across the entire 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 | 2ft x 2ft baffle is built
into the wall with horn front mounted | Carver PM-120 amplifier | 2700 cu.ft. chamber
with fiberglass on all six surfaces (three with custom-made wedges).
