Description
The Electro-Voice Eliminator Monitor is a 300-
watt 2-way floor monitor that incorporates
Electro-Voice's exclusive ring mode decoupling
(RMD™) technology. The Eliminator monitor
features a constant directivity 80° x 55° horn in
a vertical orientation that provides usable moni-
tor angles of 50° and 65°. The combined pro-
fessional quality Electro-Voice manufactured
components arrange in a horizontal array with
a very durable/road worthy light weight enclo-
sure. The result is a very high performance sys-
tem with excellent vocal reproduction and ex-
tended bass response.
The Eliminator monitor incorporates Electro-
Voice's exclusive ring mode decoupling tech-
nology. This technology deals with the com-
mon resonance or "ringing modes" found in all
loudspeaker systems. It deals with mechanical
modes utilizing mechanical solutions, and deals
with acoustical resonant or ringing modes uti-
lizing acoustical solutions. The result is sub-
stantially cleaner vocal reproduction and a re-
sponse that is more uniform regardless of input
level conditions.
The system uses the newly developed
DL15BFH low frequency driver to provide
both extended low frequency response and
cleaner fundamental vocal reproduction. It also
utilizes the DH2010A high frequency pure Ti-
tanium driver coupled to a constant directivity
80° x 55° horn to produce extended high fre-
quency response and low distortion upper vo-
cal reproduction.
The Eliminator monitor features a self resetting
high frequency protection circuit, EV's PRO™
circuit. This is included with the high quality
passive network to prevent accidental high fre-
quency overload and improve system reliabil-
ity. The bass section of the Eliminator monitor
is designed using Thiele Small optimized pa-
rameters for a solid performance to 77 Hz. In
addition to including RMD techniques, the 15''
(381 mm) DL15BFH woofer is specially designed
to provide extended 300-watt continuous
(1200-watt peak) power handling. These power
handling ratings are achieved using a 6 dB
crest factor which provides peak levels 4 times
that above the continuous rating of 300-watts.
The Eliminator Monitor also features a stand
mount adapter on the woofer side for vertical
orientation (standard 1 3/8 diameter.)
Speaker Protection
The Eliminator monitor, like all other vented sys-
tems, experiences rapidly increasing cone ex-
cursion below the box-tuning frequency, while
the acoustic output decreases rapidly. There-
fore, to protect the Eliminator Monitor and maxi-
mize the power output of the system, it is nec-
essary to insert an active 45- to 80-Hz high-
pass filter into the circuit. The filter should have
a slope of at least 12 dB per octave. Such
subpassband filters are found in many cross-
overs and equalizers manufactured by Electro-
Voice, as well as other commercially available
equipment.
Enclosure Construction
The Eliminator monitor enclosure is constructed
of Road-Wood™, a structural material that
combines the strength of high-quality plywood
with the density and acoustic damping of par-
ticle board without brittleness. Road-Wood™
uses the same principle of crossbanding veneers,
as in plywood, in order to achieve its very high
rigidity. A tough liquid-phenolic resin is blended
with long, narrow strands of hardwood. Al-
ternate layers are perpendicularly bonded
under intense heat and pressure to form pan-
els of superior uniformity. Unlike many grades
of plywood, Road-Wood™ is dimension-
ally stable, water resistant and free from voids.
A combination of dado-cut joints and tough
adhesives ensure a sonically dead enclosure free
