The system of an MLR (Mass Loaded Reflex) speaker downs low frequency band width applying the theory of Bass Reflex Speaker System implementing to cover quite a low bandwidth as a TV speaker. The system comprises; a resonance unit (13) reaching radiating sound to air elasticity, wave guides (11,12) formed on both sides of the resonance unit, a speaker (9) lying on one side of the wave guide to lessen the limitation of low bandwidth replay by attaching the air mass of the backward wave guide to the speaker vibrator equivalently.
