The speaker has a built-in protection circuit continuous overload. If the speaker output significantly exceeded 120 watts sinus, the speaker is cut out and the OVERLOAD indicator on the front lights up. The speaker is cut in again by pressing the button to the right of the indicator light. This protection circuit does not react to temporary signals and does not cause clipping or distortion.
Beovox MC 120.2 would handle up to 120 watts RMS power. The 20cm woofer, 7,5 mid/phase-link unit and 2,5cm dome tweeter were protected from overload by an automatic circuit. The port reflex cabinet allowed for full bass performance despite modest size. This model could be placed in a shelf system. Alternatively, optional wall-mounting brackets and floor pedestals were available.
