C 95 II features a 1" Tweeter and 2 x 6" Composite Woofer . On the other hand, the S50 features a 1" Terylene Dome Tweeter and 2 x 5.25" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
C 95 II has a frequency range of 37-24k Hz whereas S50 has a frequency range of 33-40k Hz. With a minimum frequency of 33Hz, the S50 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.

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 95 II is a 6 ohms speaker compared to the S50 which has a nominal impedance of 8 ohms.
On the other hand, they have the same sensitivity of 89 dBdB.

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 95 II can handle a max power of 165 watts RMS from the amp the whereas S50 has a max power handling value of 150 watts RMS, 15 watts less than the C 95 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
Both C 95 II and S50 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
C 95 II has a rear firing port whereas S50 has a bottom firing ports. Polk S50's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Jamo C 95 II with its rear-firing port.
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 95 II's and Polk S50'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 Polk S50 has external dimensions of 951.0 x 262.0 x 281.0mm ( 37-7/16 x 10-5/16 x 11-1/16inch) .
Polk S50 is 31mm shorter and 102mm less deeper than Jamo C 95 II but it is also 15mm wider.
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 Polk S50 is approximately 736.2cm2 / 114.1inch2. The C 95 II requires 28% more surface area than the S50 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 Polk S50 weighs 14.50kg / 31.9lbs. This makes the C 95 II 37% heavier than the S50.
Here is a comparison of how C 95 II and S50's weights compare with the average, max and min weights in Passive Floor-standing class.
