Description
The Electro-Voice Eliminator
®
 Monitor is a
350-watt 2-way floor monitor that incorpo-
rates Electro-Voice's exclusive ring mode
decoupling (RMD™) technology.  The
Eliminator monitor features a constant di-
rectivity 80° x 55° horn in a vertical orienta-
tion that provides usable monitor angles
of 50° and 65°.  The combined professional
quality Electro-Voice manufactured com-
ponents arrange in a horizontal array with
a very durable/road worthy light weight
enclosure.  The result is a very high per-
formance system with excellent vocal
reproduction and extended bass response.
The Eliminator Monitor incorporates
Electro-Voice's exclusive ring mode
decoupling technology.  This technology
deals with the common resonance or "ring-
ing modes" found in all loudspeaker sys-
tems.  It deals with mechanical modes uti-
lizing mechanical solutions, and deals with
acoustical resonant or ringing modes uti-
lizing acoustical solutions.  The result is
substantially cleaner vocal reproduction
and a response 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 reproduc-
tion.  It also utilizes the DH2010A high
frequency pure Titanium driver coupled
to a constant directivity 80° x 55° horn to
produce extended high frequency
response and low distortion upper vocal
reproduction.
The Eliminator Monitor features a self re-
setting high frequency protection circuit,
EV's PRO™ circuit.  This is included with
the high quality passive network to pre-
vent accidental high frequency overload
and improve system reliability.  The bass
section of the Eliminator Monitor is de-
signed 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 spe-
cially designed to provide extended 350-watt
continuous   (1200-watt peak) power han-
dling.  These power handling ratings are
achieved using a 6 dB crest factor which
provides peak levels 4 times that above the
continuous rating of 350-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 systems, experiences rapidly in-
creasing cone excursion below the box-
tuning frequency, while the acoustic out-
put decreases rapidly.  Therefore, to pro-
tect the Eliminator Monitor and maximize
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
crossovers and equalizers manufactured
by Electro-Voice, as well as other commer-
cially available equipment.
Enclosure Construction
The Eliminator Monitor enclosure is con-
structed of Road-Wood™, a structural
material that combines the strength of high-
quality plywood with the density and
acoustic damping of particle board with-
out 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
