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.
Ultra Bookshelf can handle a max power of 150 watts RMS from the amp the whereas Debut 2.0 B6.2 has a max power handling value of 120 watts RMS, 30 watts less than the Ultra Bookshelf.
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.
