Drivers
One of the fundamental differences between these two speakers is that 265-LS is a 3-way design whereas the R-5800-W II is a 2-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.

In-wall Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
265-LS and R-5800-W II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 265-LS sensitivity is rated at 91 dB and the R-5800-W II's is at 94 dB. This 3 dB difference makes the Klipsch R-5800-W II a more sensitive speaker compared to Polk Audio 265-LS, hence will play louder with the same amount of watts.

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.
265-LS can handle a max power of 200 watts RMS from the amp the whereas R-5800-W II has a max power handling value of 50 watts RMS, 150 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
265-LS features Spring post type posts and R-5800-W II has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons.
