Eliminator i
™
General Product Description
The Electro-Voice Eliminator i
™
is a high-peak output,
high-efficiency two-way stage system. The 15-in.
low-frequency/hor n-loaded constant-directivity
high-frequency system incorporates elements of Ring-Mode
Decoupling (RMD
TM
). RMD techniques substantially improve
vocal fundamental intelligibility and produce an “up front”
tonality capable of cutting through even difficult acoustic
environments.
The Eliminator i
™
enclosure has a unique design that
presents a very minimal frontal cross section while still
maintaining substantial internal volume. A newly developed
handle concept allows for extremely comfor table
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
™
’s high performance design is the
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
™
uses RMD
™
to control several
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
™
Sub, which can be used in either
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
™
should be
high-pass filtered to reduce subsonic material below 40 Hz.
Architects’ and Engineers’ 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.
