General Product Description
The Electro-Voice Eliminator i™ is a high-peak output,
high-efficiency two-way stage system. The 15-in.
low-frequency/horn-loaded constant-directivity
high-frequency system incorporates elements of Ring-Mode
Decoupling (RMD
vocal fundamental intelligibility and produce an “up front”
tonality capable of cutting through even difficult acoustic
environments.
The Eliminator i
presents a very minimal frontal cross section while still
maintaining substantial internal volume. A newly developed
handle concept allows for extremely comfortable
transportation from any orientation. The design is light weight,
but very rugged and features a heavy metal grille and highly
stylized corner protection.
The heart of Eliminator i
combination of a high-excursion low-frequency suspension
system with Electro-Voice’s unique Ring-Mode Decoupling.
All loudspeaker drivers exhibit mechanical resonance modes
that add their own time-domain or ringing-mode colorations.
These colorations limit and reduce overall system
intelligibility. The Eliminator i
fundamental mechanical ringing modes. The result is
substantially improved vocal range intelligibility and system
“openness”. When extended low-frequency operation is
required, the performance can be further enhanced with the
use of the Eliminator i
biamp or full-range passive mode. Vented enclosures offer
excellent power handling and low distortion in the lowest
octave of rated operation. However, it is always advisable to
filter material below enclosure tuning to further improve
system output and headroom. The Eliminator i
high-pass filtered to reduce subsonic material below 40 Hz.

Architects’ and Engineer s’ Specifications
The loudspeaker system shall consist of a 38.1-cm (15-inch)
low-frequency transducer in a vented enclosure. The
high-frequency section shall be a compression driver with a
pure titanium diaphragm coupled to a 1-inch throat diameter
to a constant-directivity horn having a horizontal included
angle (as referenced to -6 dB) of 60° and a vertical included
angle of 40° nominal. The loudspeaker shall have a rated
frequency response of 50 Hz to 20 kHz ±3 dB and a long-term
rated average power handling of 350 watts (EIA RS-426-A).
The system sensitivity shall be 99 dB when measured in an
anechoic environment with a 1-watt input with a calibrated
measurement microphone located 1 meter from the system
axis. The nominal impedance shall be 8 ohms. The system
shall have parallel 1/4-in. phone jacks. The system shall
include a 1 3/8-in. stand-mount adapter.

Power -Handling Capacity
Electro-Voice components and systems are manufactured to
exacting standards, ensuring they will hold up, not only through
the most rigorous of power tests, but also through continued use in
arduous, real-life conditions. The EIA Loudspeaker Power Rating
Full Range (ANSI/EIA RS-426-A 1980) uses a noise spectrum that
mimics typical music and tests the thermal and mechanical
capabilities of the components. Electro-Voice will support relevant
additional standards as and when they become available. Extreme,
in-house power tests, which push the performance boundaries of
the woofers, are also performed and passed to ensure years of
trouble-free service.
Specifically, the Eliminator i
with the following values:
= 5.175 ohms (1.15 x RE)
R
SR
P
= 350 watts
E(MAX)
Test voltage = 42.55 volts rms,
The “peak” power-handling capacity of a woofer is determined by
the peak test voltage amount. For the Eliminator i
peak-test voltage translates into 1,400-watts short-term peak powerhandling capacity. This is the equivalent of four times the “average”
™
passes ANSI/ EIA RS-426-A 1980
85.10 volts peak (+6 dB)
™
a 85.10-volt-
power-handling capacity, and is a peak that can be sustained for
only a few milliseconds. However, this sort of short duration peak is
very typical in speech and music. Provided the amplifier can
reproduce the signal accurately, without clipping, the woofer will
also perform accurately and reliably, even at these levels.
Amplifier Recommendations
The power-handling rating of the Eliminator i™ is 350-watts
continuous. The specific tests used employ a crest factor (ratio of
peak energy to continuous energy of at least 6 dB). During extended
testing, the Eliminator i
™
is routinely subjected to peak levels far in
excess of its continuous rating of 350 watts. Many amplifier designs
are capable of producing peak power levels in excess of their ratings
as well, so exact “pairing” of loudspeaker rating and amplifier ratings
is not necessary. Amplifier continuous ratings of 250 watts to 400
watts are suggested. Larger amplifier ratings are recommended
for maximum dynamic range, but it should be recommended that
amplifier continuous levels (as opposed to peak levels) be within
the range quoted for the Eliminator i
™
long-term average
power-handling rating.
Stand Mounting
The Eliminator i™ is equipped with an internal stand-mount adapter
that will accommodate standard 1 3/8-in. diameter speaker stands.
