DESCRIPTION
In the decade or more since the introduction of compact
speaker systems, performance has improved dramatically
through a series of subtle refinements in materials,
engineering knowledge, and production techniques. The
result of this continuing advancement has been pro-
gressively better sound at ever lower costs, and the E-V
FOURTEEN loudspeaker system is a case in point.
An acoustic suspension woofer must have an extremely
low free-air resonance so that the additional restoring
force of the air sealed in the enclosure will raise the
operating resonance to the desired frequency. The E-V
FOURTEEN woofer has a free-air resonance of 25 Hz. A
sealed, urethane foam half-roll surround maintains precise
alienment of the cone without unnecessarily raising the
resonance.
From 1500 Hz to the limit of audibility, a special
2%-inch cone tweeter provides the sparkle and brilliance
so necessary for satisfying musical reproduction. The use
of a relatively large diameter cone maintains the neces-
sary efficiency down to the lower limit of the tweeter's
range. However, unlike some tweeters, the flat-cone
geometry and aluminum dome maintain wide dispersion
for complete coverage of the listening area.
A deluxe LCR crossover controls the input to each of the
drivers. and provides adjustment of high-frequency re-
sponse to match listening room acoustics. The crossover
and all components are tested individually, and then as a
complete system, to assure laboratory standard per-
formance.
The E-V FOURTEEN enclosure integrates the require-
ments 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, which is held in
place by an adhesive backing, may be repositioned for
vertical placement.

PLACEMENT
The E-V FOURTEEN 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 equal to the
listener's ear level. The E-V FOURTEEN performs
equally well placed in a horizontal or vertical position.
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 in Figure |. A
distance of six to eight feet between stereo speakers will,
in most rooms, provide natural separation. Placing the
loudspeakers 100 close together or listening at too great a
distance will destroy the stereo effect, and the sound 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 FOURTEEN has a nominal impedance of eight
ohms. Connections should be made between the right
terminal and the amplifier 8-ohm terminal; the left
terminal 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 FOURTEEN 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-
“HOLE IN THE frequency reflection. In “soft” or “dead” rooms with
MIDDLE" carpeting, soft furniture, and draperies, an advanced
ss setting of the contro! 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 satisfactory to
you is correct.
CUSTOMER SERVICE
Your E-V FOURTEEN has been packed to provide
protection well in excess of shipping requirements of the
Interstate Commerce Commission. If shipping damage
occurs, contact the dealer from whom the unit was
purchased or the carrier and request inspection and
further instructions.
