R-41M features a 1" Tractrix Horn Tweeter and 1 x 4" Copper-spun IMG Woofer with a Crossover frequency at 1730Hz. On the other hand, the R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer .
Frequency Response
R-41M has a frequency range of 68-21k Hz whereas R-820F has a frequency range of 35-21k Hz. With a minimum frequency of 35Hz, the R-820F can go significantly deeper on the low side and provide stronger bass compared to the R-41M's min frequency of 68Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

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
R-41M and R-820F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-41M sensitivity is rated at 90 dB and the R-820F's is at 97 dB. This 7 dB difference makes the Klipsch R-820F a more sensitive speaker compared to Klipsch R-41M, 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.
R-41M can handle a max power of 150 watts RMS from the amp the whereas R-41M has a max power handling value of 50 watts RMS , 100 watts less than the R-820F.
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
R-41M features Post type posts and R-820F has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
