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.
Motion B10 can handle a max power of 200 watts RMS from the amp the whereas Debut 2.0 B6.2 has a max power handling value of 120 watts RMS, 80 watts less than the Motion B10.
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
Motion B10 features 5-Way post type posts and Debut 2.0 B6.2 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.
