The Electro-Voice Eliminator i™ Sub is a single 18 inch subwoofer
system designed to produce very high-peak output musical material.
The Eliminator i™ Sub can be used either in conventional biamplified
operation or in full-range passive mode w/the Eliminator i™
two-way high-peak output stage system in parallel. When used in
parallel, the combined impedance is 4 ohms. The internal passive
crossover consists of low-pass filter to the 18-in. DL18BFH.
The system is designed for operation up to 100 Hz (in passive
mode). The system can also be used in biamp mode by using an
active crossover system w/slopes of 24 dB per-octave.
Recommended crossover point is 80 Hz when used w/a
loudspeaker processor/crossover capable of low frequency
protection; or, as this is a vented system, a 40 Hz low frequency
filter of @ least 3rd or 4th order is recommended (18 dB/ octave to
24 dB/octave) to filter out signals below that frequency.
The Eliminator i™ Sub includes a top-mounted stand adapter and
an 18 in. pole mount for use w/the Eliminator i™ full-range system.
Safety concerns limit the use of a pole greater than 18 inches in
length (under no circumstances should a pole of greater than 18
inches be used w/the Eliminator i™ Sub). The DL18BFH woofer
will provide average power handling ratings of 400 watts EIA and
peak power ratings of 800 to 1000 watts. The system input
connections are 1/4-in. phone. Vented enclosures offer excellent
power handling & 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 & headroom.
The Eliminator i™ should be high-pass filtered to reduce subsonic
material below 40 Hz.
