General Product Description

The Electro-Voice® Eliminator ii™ is a high-peak output, high­efficiency two-way stage system. The dual 15 in. low-frequency/
horn-loaded constant-directivity high-frequency system incorporates
elements of Ring-Mode Decoupling (RMD
substantially improve vocal fundamental intelligibility and produce
an “up front” tonality capable of cutting through even the most difficult
acoustic environments.

The Eliminator ii™ 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 comfortable transportation from any orientation. The
design is lightweight, but very rugged and features a heavy metal
grille and highly stylized corner protection.

The heart of the Eliminator ii™ ‘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 ii
to control several fundamental ringing modes. The result is
substantially improved vocal range intelligibility and system
“openness”.

Two 15 inch drivers provide very high output at the lower frequencies.
When extended high output low-frequency operation is required,
performance can be further enhanced by biamping the Eliminator
ii™ with the Eliminator i™ Sub. Vented enclosures offer excellent power
handling and low distortion in the lowest octave of rate operation.
However, it is always advisable to filter material below enclosure
tuning to further improve system output and headroom. The
Eliminator ii™ should be high-pass filtered to reduce subsonic
material below 40 Hz.

Power -Handling Capacity

To our knowledge, Electro-Voice was the first U.S. manufacturer to develop
and publish a power test closely related to real-life conditions. First, we use
a random-noise input signal because it contains many frequencies
simultaneously, just like real voice or instrument program. Second, our signal
contains more energy at extremely high and low frequencies than typical
actual program, adding an extra measure of reliability. Third, the test signal
includes not only the overall “long term average” or “continuous” level –
which our ears interpret as loudness – but also short-duration peaks which
are many times higher than the average, just like actual program. The long­term average level stresses the speaker thermally (heat). The instantaneous
peaks test mechanical reliability (cone and diaphragm excursion). Note
that the sine-wave test signals sometimes used have a much less
demanding peak value relative to their average level. In actual use, long­term average levels exist from several seconds on up, but we apply the
long-term average for several hours, adding another extra measure of
reliability.

Specifically, the Eliminator ii™ is designed to withstand the power test
described in the ANSI/EIA RS-426-A 1980. The EIA test spectrum is applied
for eight hours. To obtain the spectrum, the output of a white-noise generator
(white noise is a particular type of random noise with equal energy per
bandwidth in Hz) is fed to a shaping filter with 6-dB-per-octave slopes below
40 Hz and above 318 Hz. When measured with the usual constant­percentage bandwidth analyzer (one-third-octave), this shaping filter
produces a spectrum whose 3-dB-down points are at 100 Hz and 1,200 Hz
with a 3-dB-per-octave slope above 1,200 Hz.

Amplifier Recommendations

The power-handling rating of the Eliminator ii™ is 600-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
ii™ is routinely subjected to peak levels far in excess of its continuous
rating of 600 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 300 watts to 600 watts into 4 ohms are suggested.
