Uni-Fi 2.0 UF52 features a 1" soft dome Tweeter , a 4" Midrange and 3 x 5.25" Aluminum Woofer with a Crossover frequency at 200hZ and 2000HZ. On the other hand, the C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer .
Frequency Response
Uni-Fi 2.0 UF52 has a frequency range of 42-35k Hz whereas C 97 II has a frequency range of 32-24k 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 Uni-Fi 2.0 UF52's min frequency of 42Hz.
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
Uni-Fi 2.0 UF52 and C 97 II have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Uni-Fi 2.0 UF52 sensitivity is rated at 85 dB and the C 97 II's is at 89 dB. This 4 dB difference makes the Jamo C 97 II a more sensitive speaker compared to ELAC Uni-Fi 2.0 UF52, 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.
Uni-Fi 2.0 UF52 can handle a max power of 180 watts RMS from the amp the whereas Uni-Fi 2.0 UF52 has a max power handling value of 140 watts RMS , 40 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. Uni-Fi 2.0 UF52 has a 5-Way post which doesn't 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 ELAC Uni-Fi 2.0 UF52's and Jamo C 97 II's external dimensions. ELAC Uni-Fi 2.0 UF52 has external dimensions of 999.0 x 232.0 x 323.0mm ( 39-5/16 x 9-1/8 x 12-11/16inch) whereas 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) .
Jamo C 97 II is clearly the larger of the two speakers. Its body is 16mm wider, 71mm taller and 79mm deeper than ELAC Uni-Fi 2.0 UF52.
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 ELAC Uni-Fi 2.0 UF52 is approximately 749.4cm2 / 116.2inch2 and base area of the Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The Uni-Fi 2.0 UF52 requires 25% less surface area than the C 97 II 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 ELAC Uni-Fi 2.0 UF52 weighs 19.73kg / 43.4lbs and the Jamo C 97 II weighs 24.55kg / 54lbs. This makes the C 97 II 24% heavier than the Uni-Fi 2.0 UF52.
Here is a comparison of how Uni-Fi 2.0 UF52 and C 97 II's weights compare with the average, max and min weights in Passive Floor-standing class.
