Drivers
One of the fundamental differences between these two speakers is that C 97 II is a 3-way design whereas the TSi400 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 TSi400 features a 1" Tweeter and 3 x 5.25" Organic Fiber Woofer .
Frequency Response
C 97 II has a frequency range of 32-24k Hz whereas TSi400 has a frequency range of 44-24k 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 TSi400's min frequency of 44Hz.
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 is a 6 ohms speaker compared to the TSi400 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. C 97 II sensitivity is rated at 89 dB and the TSi400's is rated at 91 dB. This 2 dB difference makes the Polk TSi400 a more sensitive speaker compared to Jamo C 97 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 97 II can handle a max power of 200 watts RMS from the amp the whereas C 97 II has a max power handling value of 180 watts RMS , 20 watts less than the TSi400.
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 97 II and TSi400 features dual binding post speaker terminals for bi-amping or bi-wiring.
Jamo C 97 II's Posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
C 97 II has a rear firing port whereas TSi400 has a bottom firing ports. Polk TSi400's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Jamo C 97 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 97 II's and Polk TSi400'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 Polk TSi400 has external dimensions of 985.0 x 208.0 x 369.0mm ( 38-3/4 x 8-3/16 x 14-1/2inch) .
Jamo C 97 II is clearly the larger of the two speakers. Its body is 40mm wider, 85mm taller and 33mm deeper than Polk TSi400.
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 Polk TSi400 is approximately 767.5cm2 / 119.0inch2. The C 97 II requires 30% more surface area than the TSi400 which gives it a small disadvantage on placement in tight spaces.
