In this review, we will be comparing S 805 and R-820F, two Passive Floor-standing speakers from Jamo and Klipsch. Let's have a brief look at the main features
of Jamo S 805 and Klipsch R-820F first before getting into our more
detailed comparison.
What size room are the Jamo S 805 and Klipsch R-820F speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Jamo S 805 and Klipsch R-820F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

S 805 features a 1" Tweeter and 1 x 5" Aluminized Polyfiber Woofer with a Crossover frequency at 2000Hz. On the other hand, the R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer .
Frequency Response
S 805 has a frequency range of 49-26k 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 S 805's min frequency of 49Hz.
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 Floor-standing 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 805 and R-820F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. S 805 sensitivity is rated at 88 dB and the R-820F's is at 97 dB. This 9 dB difference makes the Klipsch R-820F a more sensitive speaker compared to Jamo S 805, 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 805 can handle a max power of 150 watts RMS from the amp the whereas S 805 has a max power handling value of 80 watts RMS , 70 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
S 805 features Post type posts and R-820F has a 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. In this section, we are going to compare Jamo S 805's and Klipsch R-820F's external dimensions. Jamo S 805 has external dimensions of 787.0 x 191.0 x 252.0mm ( 31-1/2 x 9-7/8 x 11-1/8inch) 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 86mm wider, 309mm taller and 174mm deeper than Jamo S 805.
Below you can see the front view size comparison of Jamo S 805 and Klipsch R-820F 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 805 is approximately 481.3cm2 / 74.6inch2 and base area of the Klipsch R-820F is approximately 1180.0cm2 / 182.9inch2. The S 805 requires 59% less surface area than the R-820F which gives it a small advantage on placement in tight spaces.
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 805 weighs 8.60kg / 18.9lbs and the Klipsch R-820F weighs 24.55kg / 54lbs. This makes the R-820F 185% heavier than the S 805.
Here is a comparison of how S 805 and R-820F's weights compare with the average, max and min weights in Passive Floor-standing class.
