Frequency Response
S 803 has a frequency range of 57-26k Hz whereas R-41M has a frequency range of 68-21k Hz. With a minimum frequency of 57Hz, the S 803 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
S 803 and R-41M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. S 803 sensitivity is rated at 87 dB and the R-41M's is at 90 dB. This 3 dB difference makes the Klipsch R-41M a more sensitive speaker compared to Jamo S 803, 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.
S 803 can handle a max power of 80 watts RMS from the amp the whereas R-41M has a max power handling value of 50 watts RMS, 30 watts less than the S 803.
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
S 803 features Single Gold Plated Binding Posts type posts and R-41M has a Single Gold Plated Binding Posts type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
S 803 has a front firing port whereas R-41M has a rear firing ports. Jamo S 803's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch R-41M with its rear-firing port.
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. In this section, we are going to compare Jamo S 803's and Klipsch R-41M's external dimensions. Jamo S 803 has external dimensions of 353.0 x 191.0 x 252.0mm ( 13.8 x 7.5 x 9.9inch) whereas Klipsch R-41M has external dimensions of 287.0 x 146.0 x 200.0mm ( 11.2 x 5.7 x 7.8inch) .
Jamo S 803 is clearly the larger of the two speakers. Its body is 45mm wider, 66mm taller and 52mm deeper than Klipsch R-41M.
Below you can see the front view size comparison of Jamo S 803 and Klipsch R-41M in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Jamo S 803 is approximately 481.3cm2 / 74.6inch2 and base area of the Klipsch R-41M is approximately 292.0cm2 / 45.3inch2. The S 803 requires 65% more surface area than the R-41M which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Jamo S 803 weighs 5.40kg / 11.9lbs and the Klipsch R-41M weighs 3.20kg / 7lbs. This makes the S 803 69% heavier than the R-41M.
Here is a comparison of how S 803 and R-41M's weights compare with the average, max and min weights in Passive Bookshelf class.
