Introduction

Thank you tor choosing the
CONCEPT Constant Energy Heil
Air»Motion Transformer speaker
system. We think you ll most
appreciate CONCEPT ir you
understand its design philosophy, so
beiore you setup your speakers, take
a few minutes and read this manual. It
contains all the necessary hook-up
information, plus a technical
discussion of what makes the
CONCEPT Constant Energy speaker
the latest step towards achieving the
ultimate in sound reproduction.

Placement

For the ideal stereo image, your
speakers should be facing the same
direction, atthe same distance from
your main listening area, and at least
5 feet apart. The Constant Energy Heii
Air-Motion Transformer of the
CONCEPT CErMOflllOI is a very wide
disperSion bipolar high-frequency
radiator, projecting equal amounts or
energy to the front and rear, and also
considerable energy to the sides and
top. This additional radiation provides
the spaciousness and depth
necessary tortruly accurate sound
reproduction. so try to avoid placing
the speakers against a wall with very
absorbent surfaces such as draperies.
The optimum distance lrom a wall will
depend on your particular room
acoustics; if possible, experiment With
the placement. Corner placement is
not recommended because it may
overemphasize and color the bass
output, and could also cause some
undesirable reflections at the midrange
and high frequencies

Connections

We recommend that you use
Its-gauge lamp cord (Zip cord") to
connect your speakers to your
amplifier or receiver. Lighterrgauge
Wire has more electrical resistance
and its use will restrict the flow of
current tothe Speakers, impairing the
high trequerioest It you need more
than Soleet of wire to reach a
speaker, use heavier, 16»gauge Cord,
(You can use heavier Wire for shorter
runs too) Both 18 and 16rgauge acid
are readily available at hardware
stores.

The connecting terminals are
located on the rear of the speaker To
make the connection clip off only
Va-inch of insulation. TWIst the strands
tightly, press in on the movable part of
the terminal, and insert the bare wire
in the hole at the back of the terminal.
Release the terminal, the spring
loading provides a safe, positive
connection.

Connect the right-hand speaker to
the nght-channel terminals on the
amplifier or receiver. Make sure the
red speaker terminal is connected to
the + terminal (usually also red) on
the receiver, The black speaker
terminal should be connected to the e
receiverterminal (usually also black).
Follow the same procedure in
connecting the left-hand speaker to
the left-channel receiver terminals,
This will insure that your speakers are
connected in phase, working together,
not in opposition, Speaker cord either
has ridges or a different color showmg
through on one side of the insulation,
so you can easily identify which side is
A andwhich is ,_
