Since speaker connections are polarized, the terminals are typically color-coded so that the positive wire connects to the red and the negative to the black terminal. The terminal consists of a spring-loaded metallic pincher that opens when the lever is pressed, and when released will tightly grip the conductor which has been inserted into it.
Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two conductors) runs from the amplifier output to the terminals at the loudspeaker housing.
Speaker wire is a passive electrical component described by its electrical impedance, Z.The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the imaginary component of the impedance: capacitance or inductance.
In a closed-box loudspeaker, the air inside the box acts as a spring, returning the cone to the zero position in the absence of a signal. A significant increase in the effective volume of a closed-box loudspeaker can be achieved by a filling of fibrous material, typically fiberglass, bonded acetate fiber (BAF) or long-fiber wool.
