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:

•Stripe on one wire

•Ribbed area you can feel on one conductor

•Different colors of metal wire on each conductor

•Fabric strand or string wound into one of the conductors
