A TRANSDUCER which converts electrical energy to acoustical energy. Very often, loudspeakers with different FREQUENCY RESPONSE characteristics are combined together in a speaker system. This is necessary for HI-FI reproduction, since it is difficult for a single loudspeaker to reproduce the entire audio spectrum.
Loudspeakers which reproduce low frequencies are called WOOFERs; those which reproduce high frequencies TWEETERs.
