What size room are the Jamo C 95 II and Klipsch R-620F 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:

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers

C 95 II features a 1" Tweeter and 2 x 6" Composite Woofer. 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
C 95 II has a frequency range of 37-24k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 37Hz, the C 95 II can go slightly deeper then the R-620F's min frequency of 38Hz.
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
C 95 II is a 6 ohms speaker compared to the R-620F which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. C 95 II sensitivity is rated at 89 dB and the R-620F's is rated at 96 dB. This 7 dB difference makes the Klipsch R-620F a more sensitive speaker compared to Jamo C 95 II, 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.
C 95 II can handle a max power of 165 watts RMS, whereas R-620F has a max power handling value of 100 watts RMS, 65 watts less than the C 95 II.
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
C 95 II features Posts posts which make bi-amping or bi-wiring possible. R-620F has a Post which doesn't feature bi-amping/bi-wiring.
Jamo C 95 II's Posts terminals allows Bi-amping or bi-wiring
Klipsch R-620F's Post terminals
Cabinet Type and Port Position
Both C 95 II and R-620F 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
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 C 95 II's and Klipsch R-620F's external dimensions. Jamo C 95 II has external dimensions of 982.0 x 247.0 x 383.0mm (38-5/8 x 9-11/16 x 15-1/16inch) 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 8mm narrower and 14mm less deeper than Jamo C 95 II but it is also 39mm taller.
Below you can see the front view size comparison of Jamo C 95 II 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 C 95 II is approximately 946.0cm2 / 146.6inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The C 95 II requires 7% more surface area than the R-620F which gives it a small disadvantage 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 C 95 II weighs 19.91kg / 43.8lbs and the Klipsch R-620F weighs 18.64kg / 41lbs. This makes the C 95 II 7% heavier than the R-620F.
Here is a comparison of how C 95 II and R-620F's weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (37Hz vs 38Hz). |
| Amplifier needs | B | Klipsch R-620F is more sensitive (96dB vs 89dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Klipsch R-620F is the easier load at 8 ohms. |
| Headroom | A | Jamo C 95 II takes more power (165W vs 100W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | A | Jamo C 95 II: bi-amping. |
| Price | evenly matched | Much the same money ($918 vs $998 a pair). |
A Jamo C 95 II 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. Match it to your room: we rate Jamo C 95 II the better fit for a large room, and Klipsch R-620F for a small room. If your amplifier is modest, vintage or valve-based, Klipsch R-620F is the safer partner - the other will want more current or more watts to sound its best.
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.
