Frequency Response
XT70 has a frequency range of 35-40k Hz whereas C 95 II has a frequency range of 37-24k Hz. With a minimum frequency of 35Hz, the XT70 can go slightly deeper then the C 95 II's min frequency of 37Hz.
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.

High Frequency
Floor-standing Speakers
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
XT70 is a 8 ohms speaker compared to the C 95 II which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. XT70 sensitivity is rated at 86 dB and the C 95 II's is rated at 89 dB. This 3 dB difference makes the Jamo C 95 II a more sensitive speaker compared to Polk XT70, 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.
XT70 can handle a max power of 200 watts RMS from the amp the whereas C 95 II has a max power handling value of 165 watts RMS, 35 watts less than the XT70.
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 95 II features Posts posts which make bi-amping or bi-wiring possible. XT70 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
Jamo C 95 II's Posts terminals allows Bi-amping or 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 Polk XT70's and Jamo C 95 II's external dimensions. Polk XT70 has external dimensions of 1031.0 x 275.0 x 340.0mm ( 40-9/16 x 10-13/16 x 13-3/8inch) whereas 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) .
Jamo C 95 II is 28mm narrower and 49mm shorter than Polk XT70 but it is also 43mm 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 Polk XT70 is approximately 935.0cm2 / 144.9inch2 and base area of the Jamo C 95 II is approximately 946.0cm2 / 146.6inch2. The XT70 requires 1% less surface area than the C 95 II which gives it a small advantage on placement in tight spaces.
