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-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
S 805 has a frequency range of 49-26k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-620F can go significantly deeper on the low side and provide stronger bass compared to the S 805's min frequency of 49Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
S 805 and R-620F 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-620F's is at 96 dB. This 8 dB difference makes the Klipsch R-620F a more sensitive speaker compared to Jamo S 805, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing 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-620F can handle a max power of 100 watts RMS, whereas S 805 has a max power handling value of 80 watts RMS, 20 watts less than the R-620F.
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
S 805 features Post type posts and R-620F has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
S 805 has a front firing port whereas R-620F has a rear firing ports. Jamo S 805's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch R-620F with its rear-firing port.

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 Jamo S 805's and Klipsch R-620F's external dimensions. Jamo S 805 has external dimensions of 787 x 191 x 252 mm (31 x 7-1/2 x 9-15/16 inch) whereas Klipsch R-620F has external dimensions of 1021.0 x 239.0 x 369.0mm (40-3/16 x 9-3/8 x 14-1/2inch).
Klipsch R-620F is clearly the larger of the two speakers. Its body is 48mm wider, 234mm taller and 117mm deeper than Jamo S 805.
Below you can see the front view size comparison of Jamo S 805 and Klipsch R-620F 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-620F is approximately 881.9cm2 / 136.7inch2. The S 805 requires 45% less surface area than the R-620F 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-620F weighs 18.64kg / 41lbs. This makes the R-620F 117% heavier than the S 805.
Here is a comparison of how S 805 and R-620F's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Klipsch R-620F costs roughly 2.9x what Jamo S 805 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | Klipsch R-620F digs deeper - 38Hz against 49Hz. |
| Amplifier needs | B | Klipsch R-620F is more sensitive (96dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | B | Klipsch R-620F takes more power (100W vs 80W) - more in hand in a big room. |
| Size | depends | Jamo S 805 is easier to place; Klipsch R-620F is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | Jamo S 805 is cheaper - $344 against $998, about 66% less; arguably a different class. |
A Jamo S 805 B Klipsch R-620F
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Klipsch R-620F measures better, Jamo S 805 costs about about 2.9x the price% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 49Hz anyway, which makes the cheaper Jamo S 805 much easier to justify. In a large or open-plan room, Klipsch R-620F has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Jamo S 805 is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
