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.

Test voltage =
42.55 volts rms,
85.10 volts peak (+6 dB)
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 power-
handling capacity. This is the equivalent of four times the "average"

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
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
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.
