2. Note in Figure 1 that the front of the speaker is the flat surface and the rear is the "vee" surface with the angled • panels. This orientation of the speaker is important to obtain the proper distribution and reflection of sound radiated from the speaker. So, point the "vee" toward the wall. 3. The distance of the speakers from the wall is very important. For best results, the point of the "vee" should lie from 12 to 18 inches from the wall - in any case never closer than 6 inches or further than 24 inches. 4. If possible, keep the area between the speaker and the wall relatively clear and open. The sound emerging from the rear of the speakers must reach the nearby walls and re - radiate freely for the best results. 5. The ideal height of the speakers is in the range from 36 to 48 inches off the floor - the height of most musical in- struments during a concert. At a minimum, keep the speakers 12 inches from the floor. FIGURE 1 IV. Connecting the Speakers The speakers must be connected to the outputs on your amplifier (connect to the 8 ohm outputs if more than one output is available). Any good quality two -conductor wire (#18 wire size or bigger) can be used, such as ordinary lamp cord. Preserve the speaker phasing by connecting the speaker terminal marked "8a" to the "hot" or - 2-

If

keep
the

relatively
clear

The

The
ideal
height
of
the

is
in
the
range
from
36
to
48

off

-
the
height
of
most
musical
in-

during
a
concert.
At
a
minimum,
keep
the
speakers
12
inches
from
