CONNECTIONS
CAUTION: Make sure that all of the system’s electrical components are turned OFF (and preferably
unplugged from their AC outlets) before making any connections.
Speakers and ampliers have corresponding positive and negative (“+” and “–”)

connection terminals. The 4312SE has color-coded connection terminals. The “+”
terminal is red, while the “–” terminal is black. See the illustration on the right.
The 4312SE is designed so that a positive voltage at the “+” (red) terminal will cause
the speaker drivers to move outward (toward the room).
We recommend using a high-quality speaker cable with polarity coding. The side of
the cable with a ridge or other coding is usually considered positive polarity (“+”).
To ensure proper polarity, connect each “+” terminal on the back of the amplier or
receiver to the respective “+” (red) terminal on each speaker. Connect the “–” (black)
terminals in a similar way. See your receiver or amplier’s owner’s manual to conrm
its connection procedures.
BASIC SINGLE-WIRE CONNECTION

IMPORTANT: Do not reverse polarities
(i.e., “+” to “–” or “–” to “+”) when making
connections. Doing so will cause poor stereo
imaging and diminished bass performance.
The 4312SE’s gold-plated speaker terminals can
accept a variety of wire connector types: bare
wire, spade connectors, pin connectors and
banana connectors.
