Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both R-41M and R-820F are 2-way speakers.

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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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.
Sensitivity
Bookshelf Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
R-820F can handle a max power of 150 watts RMS, whereas R-41M has a max power handling value of 50 watts RMS, 100 watts less than the R-820F.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
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.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Klipsch R-41M's and Klipsch R-820F's external dimensions. Klipsch R-41M has external dimensions of 287.0 x 146.0 x 200.0mm (11.2 x 5.7 x 7.8inch) whereas Klipsch R-820F has external dimensions of 1096.0 x 277.0 x 426.0mm (43-1/8 x 10-7/8 x 16-3/4inch).
Klipsch R-820F is clearly the larger of the two speakers. Its body is 131mm wider, 809mm taller and 226mm deeper than Klipsch R-41M.
Below you can see the front view size comparison of Klipsch R-41M and Klipsch R-820F in scale.
