Frequency Response
SS-CS8 has a frequency range of 55-25k Hz whereas C 9 CEN II has a frequency range of 55-24k Hz.
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 Center Channel 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
SS-CS8 and C 9 CEN II have the same Impedance of 6 ohms but where they differ is the sensitivity levels. SS-CS8 sensitivity is rated at 86 dB and the C 9 CEN II's is at 88 dB. This 2 dB difference makes the Jamo C 9 CEN II a more sensitive speaker compared to Sony SS-CS8, 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.
SS-CS8 can handle a max power of 145 watts RMS from the amp the whereas C 9 CEN II has a max power handling value of 140 watts RMS, 5 watts less than the SS-CS8.
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
SS-CS8 features 5-Way post type posts and C 9 CEN II has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both SS-CS8 and C 9 CEN II 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 Sony SS-CS8's and Jamo C 9 CEN II's external dimensions. Sony SS-CS8 has external dimensions of 146.0 x 430.0 x 220.0mm ( 5.75 x 16.93 x 8.66inch) whereas Jamo C 9 CEN II has external dimensions of 183.0 x 466.0 x 231.0mm ( 7-3/16 x 18-5/16 x 9-1/16inch) .
Jamo C 9 CEN II is clearly the larger of the two speakers. Its body is 36mm wider, 37mm taller and 11mm deeper than Sony SS-CS8.
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 Sony SS-CS8 is approximately 946.0cm2 / 146.6inch2 and base area of the Jamo C 9 CEN II is approximately 1076.5cm2 / 166.9inch2. The SS-CS8 requires 12% less surface area than the C 9 CEN 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 Sony SS-CS8 weighs 5.00kg / 11lbs and the Jamo C 9 CEN II weighs 3.09kg / 6.8lbs. This makes the SS-CS8 62% heavier than the C 9 CEN II.
Here is a comparison of how SS-CS8 and C 9 CEN II's weights compare with the average, max and min weights in Passive Center Channel class.
