ChECkING LOUdSPEAkER PhASE

Loudspeaker wire has two conductors. On both your loudspeaker and ampliﬁer, one conductor

is attached to the negative (–) terminals, while the other is attached to the positive (+) terminals.

Usually, the wire is marked for your convenience, but the marking can be done in the following

different ways:

Of course, there are some wires that appear completely identical. So be careful, or you might make

a connection mistake. If you do, one loudspeaker will be playing “out-of-phase” with the other

loudspeaker. A pair of out-of-phase loudspeakers works against each other, and the sound of the

two playing together will be lacking in bass and sound “phasey.” If you suspect the sound is not

right, and you cannot see any markings on the wire, try this simple test:

1 2 ... 13 14 15 16 17 18 19 20 21 22 23 24
