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.
CP-WT140LCR can handle a max power of 100 watts RMS from the amp the whereas Arena 6IW has a max power handling value of 80 watts RMS, 20 watts less than the CP-WT140LCR.
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
CP-WT140LCR features Spring post type posts and Arena 6IW has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
