Full-range speaker
loudspeaker driver which reproduces as much of the audible frequency range as possible
Full-range speaker is a type of loudspeaker that can be used to play sound at all or almost all frequencies that humans are able to hear. The frequency range can be anywhere from 55 to 17500 Hertz. The benefit is that all sound comes from the same point besides multi-way speakers. Also, audio crossover can be more simple.
