Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Jamo C 97 II and Jamo C 93 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 97 II is a 3-way design whereas the C 93 II is a 2-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 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer . On the other hand, the C 93 II features a 1" Soft-Dome Tweeter and 1 x 6" Composite Woofer .
Frequency Response
C 97 II has a frequency range of 32-24k Hz whereas C 93 II has a frequency range of 45-24k 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 93 II's min frequency of 45Hz.
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 97 II and C 93 II have the same Impedance of 6 ohms but where they differ is the sensitivity levels. C 97 II sensitivity is rated at 89 dB and the C 93 II's is at 86 dB. This 1 dB difference makes the Jamo C 97 II a more sensitive speaker compared to Jamo C 93 II, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
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 97 II can handle a max power of 180 watts RMS from the amp the whereas C 93 II has a max power handling value of 120 watts RMS, 60 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 93 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 97 II and C 93 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 97 II's and Jamo C 93 II's external dimensions. 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) whereas Jamo C 93 II has external dimensions of 350.0 x 200.0 x 259.0mm ( 13.7 x 7.8 x 10.1inch) .
Jamo C 97 II is clearly the larger of the two speakers. Its body is 48mm wider, 720mm taller and 143mm deeper than Jamo C 93 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 C 97 II is approximately 997.0cm2 / 154.5inch2 and base area of the Jamo C 93 II is approximately 518.0cm2 / 80.3inch2. The C 97 II requires 92% more surface area than the C 93 II which gives it a small disadvantage on placement in tight spaces.
