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.
C 93 II can handle a max power of 140 watts RMS from the amp the whereas C 93 II has a max power handling value of 120 watts RMS , 20 watts less than the C 9 CEN II.
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.

If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
