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 amplifiers have corresponding positive and negative (“+” and “–”)
Negative (–)

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 amplifier or
receiver to the respective “+” (red) terminal on each speaker. Connect the “–” (black)
terminals in a similar way. See your receiver or amplifier’s owner’s manual to confirm
its connection procedures.

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.
