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.
Studio 2 55IW can handle a max power of 120 watts RMS from the amp the whereas CWM652 has a max power handling value of 100 watts RMS, 20 watts less than the Studio 2 55IW.
