Drivers
One of the fundamental differences between these two speakers is that CP-WT240LCR is a 2-way design whereas the 265-LS is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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-WT240LCR can handle a max power of 200 watts RMS from the amp the whereas CP-WT240LCR has a max power handling value of 100 watts RMS , 100 watts less than the 265-LS.
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-WT240LCR features Spring post type posts and 265-LS has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
