S 83 CEN features a 1" soft dome with an integrated waveguide Tweeter and 2 x 5" polyfiber Woofer with a Crossover frequency at 2000Hz. On the other hand, the C 9 CEN II features a 1" soft dome with an integrated waveguide Tweeter and 2 x 4" HCCC (Hybrid Composition Conical Cone) Woofer .
Frequency Response
S 83 CEN has a frequency range of 65-26k Hz whereas C 9 CEN II has a frequency range of 55-24k Hz. With a minimum frequency of 55Hz, the C 9 CEN II can go significantly deeper on the low side and provide stronger bass compared to the S 83 CEN's min frequency of 65Hz.
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.
Low Frequency
Center Channel Speakers
High Frequency
Center Channel 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
S 83 CEN is a 8 ohms speaker compared to the C 9 CEN II which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. S 83 CEN sensitivity is rated at 87 dB and the C 9 CEN II's is rated at 88 dB. This 1 dB difference makes the Jamo C 9 CEN II a more sensitive speaker compared to Jamo S 83 CEN, 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.
S 83 CEN can handle a max power of 140 watts RMS from the amp the whereas S 83 CEN has a max power handling value of 80 watts RMS , 60 watts less than the C 9 CEN 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
S 83 CEN 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 S 83 CEN 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 Jamo S 83 CEN's and Jamo C 9 CEN II's external dimensions. Jamo S 83 CEN has external dimensions of 216.0 x 499.0 x 247.0mm ( 8-1/2 x 19-5/8 x 9-11/16inch) 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 S 83 CEN is clearly the larger of the two speakers. Its body is 33mm wider, 33mm taller and 16mm deeper than Jamo C 9 CEN II.
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 S 83 CEN is approximately 1232.5cm2 / 191.0inch2 and base area of the Jamo C 9 CEN II is approximately 1076.5cm2 / 166.9inch2. The S 83 CEN requires 14% more surface area than the C 9 CEN II which gives it a small disadvantage on placement in tight spaces.
