Chora 806 features a 1" TNV2 AI/Mg inverted dome Tweeter and 1 x 6.5" Slatefiber Woofer with a Crossover frequency at 3000Hz. On the other hand, the R-51M features a 1" Tractrix Horn Tweeter and 1 x 5.25" Copper-spun IMG Woofer with a Crossover frequency at 1660Hz.
Frequency Response
Chora 806 has a frequency range of 55-28k Hz whereas R-51M has a frequency range of 62-21k Hz. With a minimum frequency of 58Hz, the Chora 806 can go slightly deeper then the R-51M's min frequency of 62Hz.
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
Chora 806 and R-51M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Chora 806 sensitivity is rated at 89 dB and the R-51M's is at 93 dB. This 4 dB difference makes the Klipsch R-51M a more sensitive speaker compared to Focal Chora 806, 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.
Chora 806 can handle a max power of 120 watts RMS from the amp the whereas R-51M has a max power handling value of 85 watts RMS, 35 watts less than the Chora 806.
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
Chora 806 features Single Gold Plated Binding Posts - 5-way type posts and R-51M has a Single Gold Plated Binding Posts - 5-way type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Chora 806 and R-51M have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Focal Chora 806's and Klipsch R-51M's external dimensions. Focal Chora 806 has external dimensions of 431.0 x 210.0 x 270.0mm ( 17 x 8.25 x 10.7inch) whereas Klipsch R-51M has external dimensions of 338.0 x 178.0 x 215.0mm ( 13.3 x 7.0 x 8.4inch) .
Focal Chora 806 is clearly the larger of the two speakers. Its body is 32mm wider, 93mm taller and 55mm deeper than Klipsch R-51M.
Below you can see the front view size comparison of Focal Chora 806 and Klipsch R-51M 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 Focal Chora 806 is approximately 567.0cm2 / 87.9inch2 and base area of the Klipsch R-51M is approximately 382.7cm2 / 59.3inch2. The Chora 806 requires 48% more surface area than the R-51M 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 Focal Chora 806 weighs 7.35kg / 16.2lbs and the Klipsch R-51M weighs 5.00kg / 11lbs. This makes the Chora 806 47% heavier than the R-51M.
Here is a comparison of how Chora 806 and R-51M's weights compare with the average, max and min weights in Passive Bookshelf class.
