DESCRIPTION
Representing an entirely new approach to loudspeaker
system design, the E-V FIVE-C provides performance
formerly found only in far more expensive systems. The
ten-inch woofer, two and one-half-inch tweeter and RLC
crossover created for the E-V FIVE C have been tested as
individual components and then as.an integral part of the
completed system, assuring performance equal to the
laboratory standard.
An acoustic-suspension woofer requires more moving
mass than a conventional speaker for good low-frequency
response. The required mass is supplied in the E-V
FIVE-C wooter by adding two additional layers of wire
to the voice coil. More turns of wire in the magnetic gap
maintain efficiency and offset the increased mass. The
result is bass response superior to woofers far more costly
and complex. lransient response, even near the resonant
frequency, remains clean and precise. The bass viol and
kettle drum retain their natural quality —here there is no
“juke box” bass.
Brilliant high-frequency response is assured by a new
tweeter incorporating several design innovations. While
basically a cone tweeter, it has a specially selected dust
dome mounted centrally on the cone. In the lower
portion of its frequency range, the tweeter cone and
dome together function with full efficiency. As fre-
quency increases, a progressively smaller area of the cone
radiates sound. At the highest frequencies, only the dome
is radiating. Thus maximum dispersion is maintained at
all frequencies without sacrificing efficiency. Resonant
frequency of the tweeter is just below the crossover
point, ensuring rapid rolloff, In addition, viscous damping
compound is applied to the cone compliance roll. This
semi-liquid material controls cone movement at reso-
nance and eliminates spurious responses and breakup.

The E-V FIVE-C enclosure integrates the requirements
for acoustical excellence with the techniques of fine
furniture construction. All four sides are finished in
genuine oiled walnut veneer to allow use in either vertical
or horizontal position. The nameplate may be rotated for
vertical placement.

PLACEMENT
The E-V FIVE-C may be placed on a table, shelf, or on
the floor. Generally however, the most realism will be
obtained if its height from the floor is near the listener’s
ear level. The E-V FIVE-C performs equally well placed
in a horizontal or vertical position. The nameplate may
be rotated to accommodate either placement.
The above comments apply also to stereophonic place-
ment. Additionally, however, the two systems should be
far enough apart to permit listeners to sit at the apex of a
thirty- to forty-degree angle, as illustrated. A distance of
six to eight feet between stereo speakers will, in most
rooms, provide natural separation. Placing the loud-
. Speakers too close together or listening at too great a
distance will destroy the stereo effect, and the sound
heard will be essentially monophonic. Extreme spacing
between speakers or listening at too short a distance will
produce exaggerated and unreal separation. In long

rooms, the loudspeakers should be placed along one of
the short walls facing into the long room dimension. This
improves bass reproduction and provides good stereo
listening over most of the room. '
AMPLIFIER CONNECTIONS
The E-V FIVE-C has a nominal impedance of eight ohms.
Connections should be made between the left terminal
(T1) and the amplifier 8-ohm terminal; the right terminal
(T2) should be connected to the amplifier “common”
terminal (sometimes referred to as “O” or “C”). Con-
nections should be made with No. 18 or larger wire;
common zip- or lamp-cord is satisfactory. If the speaker
leads are to be run behind a molding strip or under a
carpet, TV twin lead may be used.
ADJUSTMENT OF BALANCE CONTROL
The E-V FIVE-:C is equipped with a continuously-
variable balance control to adjust the high-frequency
response of the system to varying acoustical environ-
ments. The “normal” position, indicated on the control,
should be correct in most instances. Acoustically “hard”
or “live” rooms may require a retarded setting of the
control to compensate for the greater amount of high-
frequency reflection. In “soft” or “dead” rooms with
carpeting, soft furniture, and draperies, an advanced
setting of the control will normally be required. The best
guide to setting the control properly is a familiarity with
the sound of live music. That position of the control
which provides the musical balance most pleasing to you
is correct,
GUARANTEE
Your Electro-Voice speaker system is guaranteed for five
years from date of purchase against failures due to
defects in material or workmanship. Within this period,
Electro-Voice will repair or replace (at our option) any
defective system delivered to us or our service agency.
The unit will be returned prepaid and without charge for
material or labor. Excluded from this guarantee are
finishes and failures caused by shipping damage or
physical abuse. Operation under conditions other than
those encountered in typical installations, operation in
excess of specified ratings, or repair by other than
Electro-Voice or its authorized service agencies will void
this guarantee. Should difficulty occur, contact the
Electro-Voice Service Manager for instructions.
