Jamo Concert 9 Series History
What size room are the Jamo C 9 CEN II and Jamo C 97 II speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Jamo C 9 CEN II and Jamo C 97 II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that C 9 CEN II is a 2-way design whereas the C 97 II is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

C 9 CEN II features a 1" soft dome with an integrated waveguide Tweeter and 2 x 4" HCCC (Hybrid Composition Conical Cone) Woofer . On the other hand, the C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer .
Frequency Response
C 9 CEN II has a frequency range of 55-24k 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 C 9 CEN II's min frequency of 55Hz.
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.

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
C 9 CEN II and C 97 II have the same Impedance of 6 ohms but where they differ is the sensitivity levels. C 9 CEN II sensitivity is rated at 88 dB and the C 97 II's is at 89 dB. This 1 dB difference makes the Jamo C 97 II a more sensitive speaker compared to Jamo C 9 CEN II, 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.
C 9 CEN II can handle a max power of 180 watts RMS from the amp the whereas C 9 CEN II 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. C 9 CEN II has a 5-Way post which doesn't feature bi-amping/bi-wiring.

Jamo C 97 II's Posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both C 9 CEN II and C 97 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 C 9 CEN II's and Jamo C 97 II's external dimensions. 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) 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 9 CEN II is 887mm shorter and 171mm less deeper than Jamo C 97 II but it is also 218mm 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 9 CEN II is approximately 1076.5cm2 / 166.9inch2 and base area of the Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The C 9 CEN II requires 8% more surface area than the C 97 II which gives it a small disadvantage on placement in tight spaces.
