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.

The signal output after the amplifier stage. This is the signal to be fed to the speaker inputs.

Taken from the speaker terminals. This signal has already been amplified.

High-level audio signals travelling between an amplifier and speakers having been amplified and capable of producing output from the speakers.

Signal strength sufficient to drive speakers (greater than line level).
