MODELS: E10, E20 RIGHT LEFT Speakers and electronics terminals have corresponding positive (+) and negative (­) terminals. It is important to connect both speakers identically: positive (+) on the speaker to positive (+) on the amplifier and negative (­) on the speaker to negative (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and a poor stereo image. With the advent of multichannel surround sound systems, connecting all of the speakers in your system with the correct polarity remains as important as ever in order to preserve the proper ambience and direction- ­ + ­ + ­+ RIGHT ­ + LEFT Receiver Speaker Outputs MODEL: EC25 CENTER ­ ­ + + CENTER Receiver Speaker Outputs WALL-MOUNTING NOTICE: Important Safety Notes (Model E10 Only) the back of each screw head is about 1/8 inch (3mm) from the wall.
