Elecho Yorez” ENGINEERING DATA
DESCRIPTION
The Electro-Voice Model E-V SEVEN-B system is a
carefully designed two-way reproducer offering out-
standing performance in an enclosure of surprisingly
modest dimensions. Lower distortion and wide frequency
range are achieved by the use of two separate drivers,
each handling a special portion of the audible spectrum.
The component-quality 8-inch woofer features such
refinements as an Alnico V magnet, precision-wound
voice coil, and a linear suspension, which allows long, yet
carefully controlled, excursions.
Frequencies above 2000 Hz are handled by a three and
one-half-inch specially-constructed, cone-type tweeter
which provides exceptionally smooth treble response
without undesirable harshness. Excellent high-frequency
dispersion insures lifelike realism, especially when the
E-V SEVEN-B is used in stereo applications. A two-way
electrical crossover provides smooth transition from one
driver unit to the other. Finest quality components
including encapsulated inductors are emploved for maxi-
mum power handling capacity and crossover frequency
accuracy.
The attractive E-V SEVEN-B enclosure is rigidly con-
structed throughout and is handsomely finished in walnut
on all four sides. The nameplate may be rotated to permit
either horizontal or vertical placement.

PLACEMENT
The E-V SEVEN-B 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 SEVEN-B 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 SEVEN-B 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”), Connections should be made with No. 15 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 SEVEN-B 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 satisfactory to
you is correct.
CUSTOMER SERVICE
Your F-V SEVEN -B system 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.
GUARANTEE
Your Electro-Voice speaker system is guaranteed for five
years from date of purchase against failure 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.
