The signal that comes out of a power amplifer, intended to drive a loudspeaker. Sometimes speaker level signals are used to provide input to an amplified subwoofer from a receiver having no line level subwoofer output. See: Line Level
Speaker level is the third level of an electrical signal in a sound system. When a signal is at speaker level, it has been amplified and has reached the loudspeakers, which change the signal back into sound. Speaker level is at least ten Volts.
The moderate-voltage outputs of an amplifier or amplifier section of a receiver or integrated amplifier. While these are mainly designed to power loudspeaker systems, some subwoofers have speaker-level inputs to their built-in active or passive crossover networks. See also Line level.
