In this review, we will be comparing C 97 II and R-625FA, two Passive Floor-standing speakers from Jamo and Klipsch. Let's have a brief look at the main features
of Jamo C 97 II and Klipsch R-625FA first before getting into our more
detailed comparison.
What size room are the Jamo C 97 II and Klipsch R-625FA 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 C 97 II and Klipsch R-625FA compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that C 97 II is a 3-way design whereas the R-625FA is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer . On the other hand, the R-625FA features a 1" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
C 97 II has a frequency range of 32-24k Hz whereas R-625FA has a frequency range of 38-21k Hz. With a minimum frequency of 32Hz, the C 97 II can go significantly deeper on the low side and provide stronger bass compared to the R-625FA's min frequency of 38Hz.
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
C 97 II is a 6 ohms speaker compared to the R-625FA which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. C 97 II sensitivity is rated at 89 dB and the R-625FA's is rated at 96 dB. This 7 dB difference makes the Klipsch R-625FA a more sensitive speaker compared to Jamo C 97 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. 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.
C 97 II can handle a max power of 180 watts RMS from the amp the whereas R-625FA has a max power handling value of 100 watts RMS, 80 watts less than the C 97 II.
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
C 97 II features Posts posts which make bi-amping or bi-wiring possible. R-625FA has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both C 97 II and R-625FA 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 Jamo C 97 II's and Klipsch R-625FA's external dimensions. Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm ( 42-1/8 x 9-3/4 x 15-13/16inch) whereas Klipsch R-625FA has external dimensions of 1021.0 x 239.0 x 426.0mm ( 40-3/16 x 9-3/8 x 16-3/4inch) .
Klipsch R-625FA is 9mm narrower and 49mm shorter than Jamo C 97 II but it is also 24mm deeper.
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 97 II is approximately 997.0cm2 / 154.5inch2 and base area of the Klipsch R-625FA is approximately 1018.1cm2 / 157.8inch2. The C 97 II requires 2% less surface area than the R-625FA 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 C 97 II weighs 24.55kg / 54lbs and the Klipsch R-625FA weighs 22.20kg / 48.8lbs. This makes the C 97 II 11% heavier than the R-625FA.
Here is a comparison of how C 97 II and R-625FA's weights compare with the average, max and min weights in Passive Floor-standing class.
