Crown recommends using pre-built or profes-
sionally wired, high-quality, two-conductor,
heavy gauge speaker wire. Use bare wire, a dual
banana plug or spade lugs on the amplifier end
of each speaker cable (Figure 3.5). To prevent
the possibility of short-circuits, wrap or other-
wise insulate exposed loudspeaker cable con-
nectors.
