Definition of Speaker:] body=[
A loudspeaker (or "speaker") is an electroacoustic transducer that converts an electrical signal into sound. The speaker pulses in accordance with the variations of an electrical signal and causes sound waves to propagate through a medium such as air or water.

Loudspeakers (and other electroacoustic transducers) are the most variable elements in a modern audio system and are usually responsible for most distortion and audible differences when comparing sound systems.

Definition of Frequency Response:] body=[
(Example, 30-20,000 Hz) Describes the audible range of frequencies that an audio system will reproduce. (Note: All else being equal, the lower the low number, the better the bass response and the higher the high number, the better the treble response.)

The actual range or span of frequencies from low to high that a unit can pass or reproduce. In terms of audio recording studios, this is usually limited to the range of 20 Hz to 20,000 Hz, which represents the full range of human hearing.
