Drivers
One of the fundamental differences between these two speakers is that Studio 6 66LCR 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.
Studio 6 66LCR can handle a max power of 200 watts RMS from the amp the whereas Studio 6 66LCR has a max power handling value of 150 watts RMS , 50 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
Studio 6 66LCR features Spring post type posts and 265-LS has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
