Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Stage 280W can handle a max power of 125 watts RMS from the amp the whereas Stage 280W has a max power handling value of 120 watts RMS , 5 watts less than the A120.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Stage 280W features 5-way post type posts and A120 has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.
